<p>absolute random report !<br/><br/>I managed to get the PH down with the phosphoric acid! now I do have the PO4 levels "to high" BUT! the plants back on growing AND the fish are fine! they seem fine at least I did get a "nut burn" on the watercress, they seen to dislike the heavy harvest and "sudden" change in PH & nutrients. even so, they are coming back up and I hope so because I like the watercress I saw the burn and I almost immediately pulled out some seeds to germinate & replace the plants. some time later the plants are coming back up to I will probably not need the new seeded ones <br/><br/>Now the dump part! I've burned out all my carbonates! My KH is at Zero BUT! the PH got to about 6.7 (I overshoot on the correction, more on that later) and now the PH does not rise! I only took out some of the suspended flower beds (half of them are still there) SO I don't really understand what is up... with carbonates in water the PH rises constantly to the 8's level. now without any carbonates it does not rise a little? it just stays put!<br/><br/>I'm not to worried about the KH level being low... the PH does not have any noticeable variation. its been 2 days and it only varies about 0.05 in hours. I have a continuous PH meter and I'm taking note on the PH variation.<br/>20 mins · Like<br/>to pull the PH down I've tested with 1 Liter of water how much acid would I need to pull down the PH by 1 level. the I divided it for a few days and starting dosing the system gradually. then I got lazy so I went and got my dosing pump, a power supply & a delay relay to power the dosing pump for a few seconds right when the timed pump line kicks in! so it would add the acid right when the pump sucks it up to the GB's diluting and using it there the best I could come up with what I had around )<br/><br/>I was checking the PH evolution and correcting the dosage of acid so the PH "drop" would take a while (about 2 days objective)<br/>5 mins · Like<br/>after the 2nd day I turned off the dosing system leaving it there in case it would be needed. turns out that my PH is not coming up quickly, its staying put right at the value I left it!<br/><br/>actually... I tried to leave it at 7.0 but I overshoot to 6.7 when taking the system I dropped a few more acid from the dosing tubes<br/>so, I feel dump. with carbonates my PH just rises continuously? I don't get it.<br/><br/>Ive went from this water chem: <br/>PH: 8.0 & up<br/>EC: 2.1uS/cm (not really useful but I had the probe around)<br/>NH3: 0<br/>NO2: 0<br/>NO3: 25mg/l<br/>PO4: 0.1mg/l<br/>Potassium test: arriving tomorrow hopefully!<br/>Iron: near 1mg/l<br/>Magnesium: about 60mg/l tested and 63mg/l calculated<br/>Calcium: about 160mg/l (not rising but not lowering...)<br/>Copper: 0<br/>KH: 7º<br/>GH: 37º (660mg/l)<br/>O2: 8mg/l<br/><br/>to something like a mistake I did when replenishing the system with water... I forgot the hose open for almost 2 000 liter of water to late! :P so, all my values had a bump, and on top of that bump I've corrected "my issues" with phosphoric acid.<br/><br/>now my levels are:<br/>PH: 6.7 steady!<br/>EC: 2.0 uS/cm (not really useful but I had the probe around)<br/>NH3: 0.25 (and lowering quick)<br/>NO2: 0.15 (and lowering quick)<br/>NO3: 25mg/l<br/>PO4: +120mg/l (not precise enough due to sample dilution) <br/>Potassium test: about 80mg/l<br/>Iron: 0.5 mg/l<br/>Magnesium: about 20mg/l tested<br/>Calcium: about 40mg/l (the bump!)<br/>Copper: 0<br/>KH: 0º<br/>GH: 32º<br/>O2: 9mg/l<br/><br/>now I'm trying to void adding anything to the system that would impair even more that unbalance of PO4. but I'm really happy with the results, finally I see the plants growing again! and the PH locked in!<br/>if this continues along the way I might not need to change out the "bad leca" on my GB's :D less work & no plant loss :D<br/><br/>I'm just changing the suspended trays and I'll be adding some more of those real soon! :)<br/>I found the hydroton at a suitable price and got it!<br/><br/>now I have work to do! :D<br/>up next: tilapia food!</p> random report!

<p>- magnesium is about 60ppm so not adding it either!</p>
<p>- earthan beds made, one with plants growing (and weeds... lots of weeds since my compost was under siege by the wind and others! I don't mind cos' I like to pull the weeds :P)</p>
<p>- I'm yet to get a potassium tester "just to check it" since I'm not adding it in any way.</p>
<p>- my PH is still high even with more fish... I can't fix it right now but that crappy expanded clay will have to go!- I have no fish deaths in I don't know how long now. but I guess I have a digested fish. one of the smallest ones vanished (ornamentals)</p>
<p>- my filters are doing a pretty good job! some solids pass the radial flow filter, get trapped in the swirl filter and most of the fine solids are trapped in the trickle filter. I can't afford to place K1 media in the moving bed biofilter right now.</p>
<p>I did not find any ammonia or nitrite present in the system at any time so I actually don't need the K1 for the fish, just for helping out on the cleaning if the (pretty clean) water</p>
<p>I may be just nagging about it but I would love to have/build a filter to capture all the fines in the system...</p>
<p>- I have to clean out the sump bottom since it has some debris building up there...</p>
<p>upon checking the sump I've noticed:</p>
<p>part from the bloodworms breeding in there...</p>
<p>- I have a colony of seed shrimp (I can't see them since they are minimal but I guess its ostracods)</p>
<p>- another black'ish' worm that is eating all the unfortunate insects that drop to the bottom (unidentified)</p>
<p>- and some really tiny surface "bugs" that I can't identify due to being really small and quick!</p>
<p>I did not add any of those critters but I guess their OK to be there...</p>
<p></p>
<p>I hope I have some more news soon :)</p>
<p>wish me luck in finding some appropriate clay aggregate! (I've found hydrocorn that buffers the PH to 7.9 after about an hour. I'm going to test some others to check for the cheapest/best substrate to use.</p>

<p></p>
<p>in a few days I'll get to know if I have enough fish to pull the PH down (without building up to much nitrates) and then I'll consider changing out the leca in some GB's. I need to lower the PH bt (at least) 1 unit. its running "locked on" 8.0 right now. I can't make pretty much anything about it... as long as the water passes on all that leca (and maybe some left over carbonates in the rocks) it just buffers up.</p>
<p></p>
<p>I did find a local store with hydrocorn but I'm yet to evaluate if it is really PH neutral.</p>
<p>I've also found another store in Spain with (claimed) PH neutral hidroton.</p>
<p>I'm evaluating if I really need to replace the leca and the options available...</p>

<p>aaaaaaaaanddd I know how to make them work better. I'm just to lazy to do it yet :P</p>
<p></p>
<p>so, this "sensors" are a soft membrane pressure switch. they cannot have water inside of they will block and fail to work. they cannot be used on high pressure (since they are really sensitive)</p>
<p>we can blow on one to test it effortlessly. they are easy to scrap from dishwashers or (clothes) washing machines. we can even buy them new if we want :D</p>
<p>example 1: <a href="http://www.ebay.co.uk/itm/UNIVERSAL-AIR-PRESSURE-SWITCH-PRESSOSTAT-123-75-mm-ARISTARCO-MACH-/221728549188?pt=LH_DefaultDomain_3&hash=item33a00d2944">http://www.ebay.co.uk/itm/UNIVERSAL-AIR-PRESSURE-SWITCH-PRESSOSTAT-123-75-mm-ARISTARCO-MACH-/221728549188?pt=LH_DefaultDomain_3&hash=item33a00d2944</a></p>
<p><br/>just like the one I'm using! it came from an old machine replacement parts that I had in "stock" (that machine endured more than 18 years of heavy clothes washing! she did not fail to work... it only fell apart due to rust. it was beyond repair and kept working for a few more years (tied to a wall to keep it from running away) [back to topic]</p>
<p></p>
<p>to use it I drilled a tap into my main pump line (right before a check-valve) and added a micro irrigation nipple to connect a 6mm tube into.</p>
<p>due to the pressure created by the pipework, the pressure switch activates. giving me a clean contact to power a backup pump or a warning :D</p>
<p></p>
<p>most of them have a double trow single pole switch but sometimes we find one of this things with multiple pressure contacts (2 levels)</p>
<p>that we could use to power a backup pump and/or warn about overpressure in the pipework (maybe a blockage or just a closed tap?)</p>
<p></p>
<p>to void the water from coming into the switches I placed them high with a long 6mm tube. that way the air held in the tube acts on the membrane but the water never gets there.</p>
<p></p>
<p>to improve my connections I could have a 16mm pipe running upwards about 10 centimeters and only at the top, taping the nipple (no pun intended! but imagined for the next tree or four lines ox text :P ) that connects to the 6mm (aquarium) tube.</p>
<p>the volume of air in 10cm of the 16mm pipe is more than enough to activate the switches without getting water into them, allowing to place the pressure switches near the pumps. (mine are almost 2 meter higher than the tap... I got lazy to find another two 16mm "T" fittings but I might to it soon (to keep the water from the 6mm tube)</p>
<p></p>
<p>its good to have water in that tube as a reference of the "normal pressure" of the system... if the water in the tube goes any higher, we might have a problem in the pipework...</p>
<p></p>
<p>here is a photo of the current state: (one of the pumps only)</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772267685?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772267685?profile=original" width="697"/></a>right above the tap for the pressure switch is a check valve (actually a bunch of them for the backup pumps)</p>
<p></p>
<p>if needed I could come up with a schematic of this. a drawing would clear this up a little...</p>
<p></p>
<p>this could not work on small pumps and systems due to low pressure on the pipes... tests are mandatory before application :D</p>
<p>on huge pumps, just use a flow switch... for a 600W to 1000W pump (pool pumps or others) this could blow the membrane on the switch... I don't care if you try this, share it or sell it, just don't make me pay for problems :D</p>
<p></p>
<p>I'm using DC voltage on this units contacts (just in case)</p>
<p></p>
<p>more details if asked upon ;)</p>
<p></p>
<p>now about other things: I've finished the filters a few days ago. added the water dump lines and a vaccum/drain on the swirl filter. this way I can clean up the filters deeply without wasting almost 200Lt of water. I can clean my radial flow filter with about 20Lt of water.</p>
<p>here have a picture:</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772267878?profile=original"><img width="721" class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772267878?profile=RESIZE_1024x1024" width="721"/></a></p>
<p>the "clean water dump" lines go directly to the (still empty) moving med bio-filter (in case any debris passes trough it will be filtered) and the vaccum on the swirl filter can go directly to the "digester" or worm/compost tea brewer that I have right just there :D (its the small 30Lt barrel)I can clean the swirl filter without turning off the main pump (but its better to stop the flow and clean all the filters at once)</p>
<p></p>
<p>the radial flow filter needs to be drained (the clean water) and only at the bottom I hose down the "crap" to a bucket and then to the brewer.</p>
<p>and there they mineralise for a week or so...</p>
<p>I guess this it it for now... any hints or suggestions please share with me :D</p>

<p>populating all the fish tanks and getting the vegetables pumping! :D</p>
<p></p>
<p>I've come up with a kind of problem...</p>
<p>its starting to accumulate some debris on the bottom of my sump tank...</p>
<p>I had that on a empty fish tank but I cleaned that up with a pump sending it all to the filters.</p>
<p>and I'm proud of my filters! they were put to test when I started to pump out that debris into the filtering system. most of the large "things" are trapped on the first and second filters, passing only some really fine debris into the (empty) moving bed bio filter :P</p>
<p>(then some debris go to the sump bottom)</p>
<p></p>
<p>I'm not sure on where did all that debris came up... its quite some organic matter... when I tried to "vacuum" it to the filters, I've overwhelmed them and turned the water brow for a few hours... I don't feel its a problem but I want it fixed...</p>
<p></p>
<p>I've been checking pond vac systems to see if I could come up with a filter... I'm already using a pump to "suck" out all the gunk... I just need a filter to trap it and return clean water to the system.</p>
<p></p>
<p>does anyone have any ideas?</p>
<p>I might wonder about making a sand bio filter sometime soon... I like to have really clear water but I'm afraid that will be a little bit to hard and could trap nutrients?</p>
<p></p>
<p>please if you have any ideas, share them with me! :D</p>

<p>first of all, a picture of my ornamental fish tank :D</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772267749?profile=original"><img width="721" class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772267749?profile=RESIZE_1024x1024" width="721"/></a>we can't see them all in this photo but soon enough I'll find a way to get that in order :P</p>
<p>from the picture you can see that I have some algae...</p>
<p>I've been talking to a few guys in order to buy some chinese algae eaters (Gyrinocheilus aymonieri) and/or a pair of plecos or other smaller ones.</p>
<p>my problems are: with plecos I would have to get some wood in there. I don't have the right kind around to treat and place in the water so I would have to buy (not likely right now)</p>
<p>with the chinese algae eaters they "could" get aggressive with other fish since they are territorial and some other details. (it tell tale and reports from aquarium owners and fish stores... some say its fine, some say its not, I don't really know yet)</p>
<p></p>
<p>other problem is the temperature. not its alright but next winter I should have some solar collector and a backup heating system... (but that one I already have since I want to grow winter crops and need some higher temps for either the tilapia and or to speed up the goldfish & koi metabolism (aka protein conversion).</p>
<p>I also have a pair of "ornamental" catfish (ameiurus melas) and for now I just love them! the way this fish swim around the bottom and sometimes on the sides of half way up the tank, I just love to spend some time just looking at the fish (with a stupid smile on my face)</p>
<p></p>
<p>I guess that is a way to try to forget about the tilapias... I don't really think I'll be able to get them in the plate since I'm caring for them daily... its just like my dog, I can't eat that...</p>
<p>back to problems: the algae is purely my fault :D I leave the fish tanks open to the sun every day... I like to see the fish and I need them to regulate themselves to the solar cycle (its a little less unnatural environment for them...) so they are prone to continue to appear...</p>
<p>then... I'll need some algae eater fish (snails are an option that I have on hold. they seem to reproduce and find their way everywhere) and I'm only afraid if they turn on the other fish and cause havoc in the tank...</p>
<p>that is the worst case scenario... I tend to over complicate the simplest things... its probably going to be fine but I would love to hear from you any toughs on that? should I put algae eaters and/or plecos?</p>
<p></p>
<p>other things: I've started to install the backup-pumps either for pump failure or power outages. so I needed to "sense" the water flow from the pump aaaaaaaaaaaaaaaaaannnnnd, I taped the pump line (before an non-return valve) to a washing machine pressure switch! I'm really glad to say it works to "sense" the water flow! if the main pump fails, the back-up kicks in almost instantly, running water to the fish and filtering (hopefully helping the fish to survive and maintaining the bacteria doing their work :)</p>
<p>maybe I'm going over the top with the backup pump. I could just kick a small water pump in the fish tanks to add oxygen to the water (and that is going to be done anyway) but sensing the water pump failure with simple and cheap equipment just makes me happy! I've spent noting to add the "sensing system" and I can give the info to you! (tested! :D )</p>
<p>here a photo:<a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772267953?profile=original"><img width="721" class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772267953?profile=RESIZE_1024x1024" width="721"/></a>the switches with air line. next the check-valves manifold with the pressure sensors taps:</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772267824?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772267824?profile=original" width="714"/></a></p>
<p>I could explain that picture but I won't :D I could if anyone ask me about all those parts and what for.</p>
<p></p>
<p>on the main pump line I added a tap with micro irrigation fittings to connect to the pressure switch.</p>
<p>since the switch cannot have water inside (will stop working) I had to rise the sensors about 1.5 meters high.</p>
<p>when the pump is running, I can see the water rise in the 6mm aquarium tubing, deactivating the switch. when the pump is not running, the water returns to the normal level and the switch activates (turning on the backup pump)</p>
<p></p>
<p>a flow switch (in line with the pump) would work but I don't have one (or 2 since I have 2 pumps) and it costs more, could clog up with debris and it puts up a little more strain on the pump. this method is not perfect but it works and its really simple to check & clean.</p>
<p>every week I will make an inspection, purging any smudge from the pipes just by opening the taps :D test if the backup pumps turn on (and work properly) and then I can rest better since my back up pumps are in order! :D</p>
<p>little more checking and the system is "tested" for another week.</p>
<p></p>
<p>now other details:</p>
<p>I'm going to test out an earthan bed on a half barrel GB! here a picture:</p>
<p><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772268099?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772268099?profile=original" width="710"/></a></p>
<p>I'll have to take out some rocks from that GB in order to have the water "just at the point" and add in the other materials: shading cloth (almost like a weed mat) and the soil. just like a wicking bed I hope...</p>
<p>does anyone know: would this work? I still don't know how much area of soil VS rock I'll have there (in order to feed the soil with the water and nutrients) tomorrow I'll be able to measure and see (and tell you all about it)</p>
<p></p>
<p>I think that is all for now... (I'm out of photos on this post so I'll just add another one right up next :D</p>
<p>soon ;)</p> Hi all!

<p>Hi all!<br></br><br></br><br></br>I've been reeeeeally busy and kinda lost my north along the way but! :<br></br><br></br>I've found the source of my high PH level! and I can't really bring it down just yet...<br></br><br></br>apparently the leca I've used, after some time running in the system, started to buffer up my PH. in the beginning it was not measurable but now I can see the difference in a few hours.<br></br>since I can't change out the leca nor I can find a "better" product to use... I'll have to finish some…</p>
<p>Hi all!<br/><br/><br/>I've been reeeeeally busy and kinda lost my north along the way but! :<br/><br/>I've found the source of my high PH level! and I can't really bring it down just yet...<br/><br/>apparently the leca I've used, after some time running in the system, started to buffer up my PH. in the beginning it was not measurable but now I can see the difference in a few hours.<br/>since I can't change out the leca nor I can find a "better" product to use... I'll have to finish some issues and add more fish on the system...<br/><br/>either way, I won't manage to do it really quick... some things take time and I'm low on that. I'm having trouble sleeping for quite a while now (again) so I can't focus like I should... and I'm cold, with a cold and feeling cold xD<br/><br/>some of the plants are not growing like they should... but I've been to lazy to care for them properly... so I can understand the "revenge" either way, I was afraid of adding nutrients (calcium and magnesium) since the PH was high and could be misleading me... I don't know yet but I guess I need to add just a little and see.<br/><br/>for now: no pictures, little time, kinda stressed out and worried... but for you to "see" the peas are yellowing out. some other plants are not growing of are really slow... partially due to little sun and low temps and part for the nutrients that maybe are running low (I tend to keep low on the additions. maybe to low...)<br/><br/>but the watercress keeps taking over the DWC bed... the pepper mint has to go out to a confined space since it is taking over one GB (and trying to run into the next one)<br/><br/>I'll try to get my head on track and then my sleep cycles... and then the AP system and the photos, etc etc etc.<br/><br/>read you all soooon! (I hope! :P ) <br/><br/></p>
