<p>As to washing gravel. I usually swish a basket (plastic water plant basket) of gravel in a bin of water and then in a second cleaner bin of water then I dump it in the grow bed. The water in the system will still be cloudy for a while after filling a system. This will settle out over time, you might put an old sock or rag or something to catch some of the sediment either at the inlet to the grow bed or where the water flows back to the fish tank, whatever is easiest. …</p>

Some people use an old cloth diaper for this. But as your system starts building up a coating of bio-slime it will catch the sediment and clear the water. Patience. </p>

<p>Did the vinegar test and got nothing.. except a nasty film from the dust that was in the rocks.. which by the way is extremely difficult to get rid of. I washed each bag of the gravel before dumping it in the flow beds and have cycled almost 80 gal of water through dumping it out and restarting and still the water is cloudy.

At this point there is no fish nor plant in the system. </p>

<p>The vinegar test was done with 2 cups of gravel and 4 cups of vinegar. I mixed it well together hoping to see some bubbles.

<p>a quick test you might run with the pea gravel while you wait is to rinse some off and then drop it in a cup of vinegar. If it foams up, well then you might have a problem. If it bubbles strongly could still be a problem. If just bubbles a tiny bit, you might get by with it. No bubbling at all, should make sure it is actually vinegar and then do a little happy dance.</p>

<p>Now if the first round with the vinegar just gives a small amount of bubbling, you might let the media soak for a bit and then put it in a fresh cup of vinegar cause sometimes the media just has a coating of dust on it that might have more limestone than the actual rocks. But if it foams up like a kids volcano, don't bother with it. Use it on the ground or around plants that like alkali conditions.</p>

<p>If your 600gph pump is too strong for your barrel ponics, I thin the Quiet One 4000 will be too much too, go another size down on the quiet One pump. I think I've run a barrel ponics with a little garden pump from harbor freight that was rated for less than 300 gph and was probably only managing 50 gph at the height needed for barrel ponics. That pump costs probably $15 on sale but I think is usually about $23 or maybe $30.</p> This morning I installed a T…tag:aquaponicgardening.ning.com,2011-04-03:4778851:Comment:810892011-04-03T13:55:13.738ZJeremy Dayhttps://aquaponicgardening.ning.com/profile/JeremyDay
<p>This morning I installed a T about 20" from the outlet of the pump. One side of the T goes to the float barrel and the other goes to the fish tank. The amount of water coming off the line to the fish tank is immense. It feels like a pressure washer. I could of course drill larger holes to fix this problem but I am wondering how much flow is too much in the fish tank? I don't want to look in some day to see fish in a whirlpool. :) I have considered using the Quiet One 4000 for a pump. …</p>

I don't want to look in some day to see fish in a whirlpool. :) I have considered using the Quiet One 4000 for a pump. Still is an option as it is inexpensive. Another option would be to add hydroponics to the system to make the water travel a greater distance before it hits the float barrel. At the point the water level lin the float barrel is way above the drain pipe level and the inlet downspout. Would installing a ball valve cause the pump stress and shorten its life span? As far as media goes, I fell short on that field. I went the pea gravel stage and are waiting for my water test kit to show up from fedex. I know, I have read some of the horror stories on pea gravel and wait in anticipation to see my fate.</p> Hi Jeremy.

<p>Hi Jeremy. I'll start the ball rolling and try to answer your questions with my opines, and I'm sure others will join in with their's as well. First, congrats on the speaking engagement! Keep up the good work spreading the word about aquaponics</p>
<p>Do you have a valve inline between your pump and the float barrel? That will allow you to decrease the flow of your pump.</p>

<p>Any freshwater fish works in an aquaponic system. As you've already noted, you first need to decide if you want to eat them or not (although in <a target="_blank" href="http://theaquaponicsource.com/2010/01/15/fish-to-eat-or-not-to-eat/">a past blog post</a> I talked about how that line can be grey). Make sure that the temperature they like to live at is the temperature you can keep you system at, and if you are going to mix fish make sure they don't eat other ;-)</p>
<p>Greenhouses to me are all about climate control, and if you are in a climate where you can't grow outside year-round (as I believe you are) I'd highly recommend a greenhouse if you can afford it. The downsides are minor compared to the upside - year round growing and letting your bacteria biofilter mature over time rather than stop/start.</p>
<p>Expanded clay is nice because it is lightweight, easy on the hands, and you know exactly what you are getting. 3/4" gravel is another option, but it is twice as heavy and you need to be very careful that it is completely inert and won't affect your pH over time (no limestone!). A third option that is emerging is <a target="_blank" href="http://www.theaquaponicstore.com/Aquaponics-Expanded-Shale-Grow-Media-s/85.htm">Expanded Shale</a>. Also lightweight and easy on the hands, but less expensive that expanded clay and US mined and made.</p>

<p>to get your pump to play nice, simply plumb a bypass. That is put a T in the line that goes from the pump up to the top tank. send the offshoot of that T back into the fish tank, put a ball valve on that and the amount you open that line up will decrease the flow up to the top tank and you adjust from there. You can even put a spray bar on after the ball valve to help provide aeration in the fish tank.</p>

<p>Tilapia require rather warm water. and a barrel ponics system is rather small so maintaining a stable temperature out side is problematic in a cooler climate. If you choose a fish that will handle cooler water then you just need to keep the water from freezing in the pipes to keep your system running over winter. For a small system like that though I would say some goldfish or perhaps a few blue gill might be appropriate.</p>

<p>I use gravel, just got to ensure it is some quartz type of rock or something that won't affect system pH. Limestone or marble would be bad on the pH. I've never sprung for the clay balls.</p>
