I am attempting to start an aquaponics system with trout. I was reading about water with too much O2 from intensive vegitation causing the air bladder to distend causing the fish to float sideways. <br />
<br />
I am in a Southern California desert. Another related concern is that trout don't do well in warmer waters. Surely there is an upper limit, but it must also be dependent on O2 saturation. So is there any table somewhere to reference these limits? <br />

In essence, if I am able to get high O2 saturation, what combination with warmer than optimal water can the trout remain healthy?

<p></p>
<p>From a community perspective:</p>
<ul>
<li> a local vocational school is starting a program for both <strong>high school and adult education</strong> in <strong>aquaponics</strong></li>
<li>the <strong>local vo-ed aquaponics program</strong> is part of an environmental studies curriculum that feeds two local colleges that offer two- and four-year degrees in environmental science.</li>
<li>the vo-ed school is resurrecting an <strong>under-utilized 100' x 40' greenhouse</strong> for this purpose.</li>
<li> the <strong>vo-ed aquaponics program</strong> is emerging with help from a community garden non-profit company partly <strong>dedicated to promoting and expanding aquaponics in Butler County Ohio</strong>.</li>
<li>a local florist & garden center is shutting down their greenhouse operations for the first time in 50 years and are looking for alternatives.</li>
</ul>
<p></p>
<p>From a professional perspective:</p>
<ul>
<li>we provide <strong>instrumentation for remotely monitoring and recording temperature, humidity, pH, wetness, conductivity, liquid level</strong> with <strong>battery-operated sensors</strong> connected to a <strong>web-based portal</strong>.</li>
<li>the system will <strong>send both email and text alerts</strong> to responsible parties when <strong>any system parameter is out of compliance</strong></li>
<li>we also <strong>monitor electrical power consumption</strong> (clogged pump?) and with the same device, can turn power on or off based on other sensors inputs (for fans, pumps or any other 110AC device).</li>
</ul>
<p></p>

I have been thinking about going with a propane heater and this cinched it for me. One problem I have been dealing with that I hope somebody can help with is water temp/evaporation/mold...well obviously more than one problem. I have 3 200 watt tank heaters and with the ambient temp of around 70 degrees farinheit the water has stayed at about 65 degrees. I typically lose a third of my tank water in a month to two months time and with the evaporation the drywall is showing serious mold growth. Is there anything i can do to address these problems?

<p>I have a tank full of catfish in series with an empty tank which trout will inhabit on Monday. I need to drop the temperature on the catfish. How quickly can I do this without killing the catfish?</p>

My ammonia has been high since I added more fish a week ago and besides (probably) overloading my bacteria I am wondering if there are preferred temperatures parameters for nitrification. I have read that below 60 F diminishes efficacy (but then wondering if that is air, water, or a combination thereof).<br />

<p> Don't know if this would work (but it is what I plan on doing with my system when I get it up and running). I'm going to have a sump tank burried 4-6 feet down (where the temperature stays at a constant 50-55 degrees and has the effect of thermal cooling/heating) and have it pumped up to the surface of my fish tank that is burried half in the ground. Then i'm going to siphon the water off the bottom of my fish tank to the grow beds. My theory is... with constant 50-55 degree water…</p>

Do you guys think it will work? Oh, and one last thing...

<p>I am trying to choose which fish to stock in a commercial aquaponics system in North Alabama / Southern Middle Tennessee, where the average annual temperature is 63 degrees F.

There is likely a pretty good market for the fish, but competition may well keep the cost low, since catfish is so common (haven't checked yet). Browsing the fingerlings for sale on the Dunn's Farm website, I came across the description for Grass Carp, which sounds like they grow really fast, and are good to eat (at least the chinese think so according to Wikipedia). Anyone had experience with these, or even heard of them before? Would I feed them the same commercial feed used for catfish? (The grass carp eat mostly vegetation in the wild - hence the name.)</p>
<p> </p>
<p>I read of a system in a permaculture book where algae is grown in one section of a fish tank with a screen which keeps out the fish, but allows algae to pass through to feed the fish. I think it would be worth experimenting with a similar idea with fast growing underwater plants as feed for vegetable-eating fish.</p>
<p> </p>
<p>Any other suggestions for mild temperature loving (65 to 80 degrees), fast growing marketable fish?</p>
<p>I am also getting the impression that there is very little profit in the fish side of commercial aquaponics, and that I should plan on the profit coming from the produce. If that is really the case, then I really just need good fertilizer factories for fish. I would like to prove this idea wroing, however....</p>

Thank in advance for all your help.</p>
<p></p>
<p><strong>Background</strong>: Our aquaponic system is located at a local high school. We have 50 peppers, 100 strawberries growing in clay beads, and 10 goldfish living in two 100 gal reservoirs. We started off with more fish, but after a few attempts we decided to be content for the time being with the 10 survivors. Our pH generally runs between 7.3 and 7.6. It's a little higher than I'd like, but the water was resistant to being altered by neutralizers and pH lowering products.</p>
<p></p>
<p><strong>Problem</strong>: Two weeks ago, I cleaned and calibrated our Hanna meter. I verified the efficacy of the meter with a manual water test kit. The TDS was reading below 200, so I added about an ounce of an organic liquid fertilizer (more info about that product below) to the reservoir. I've done this before, and this has had a negligible effect on the pH. That day, as soon as I added the fertilizer, the pH jumped from 7.4 to 8.1! </p>
<p></p>
<p><strong>Treatment</strong>: Since then, we've gone through two bottles of "pH Down" and the rest of our water neutralizer. When we add the pH Down, the pH will drop from above 8.0 to about 7.6 immediately. Within an hour of application, the pH will begin to climb. Within 3 hours of application, the pH will be back where it started. I spoke with the company that makes pH Down, and their advice was to continue adding the product until the pH actually stays down.</p>
<p></p>
<p><strong>Tests</strong>: Based on a suggestion on the photo (link at beginning), a did a "vinegar test" of the clay beads the plants grow in and of the aquarium rocks that line the bottom of the reservoirs. Neither resulted in any bubbling or frothing when added to the vinegar. Earlier today I also did the following tests:</p>
<p>- Ammonium: 0 ppm</p>
<p>- Nitrite: 0 ppm</p>
<p>- Nitrate: 20 ppm</p>
<p>- TDS: 380</p>
<p>- Temperature: 88.0 F</p>
<p>- Water Source pH: 7.0</p>
<p></p>
<p><strong>Fertilizer</strong>: Since the spike occurred at the exact moment I added the fertilizer two weeks ago and hasn't come down since, it seems that more information about the product I use would be in order. </p>
<p>The fertilizer is Fox Farm "Grow Big" Hydroponic Liquid Fertilizer: <a rel="nofollow" href="http://foxfarmfertilizer.com/products_liqfert2.html" target="_blank">http://foxfarmfertilizer.com/products_liqfert2.html</a> . Until this last application, adding fertilizer had an insignificant effect on pH.</p>
<p>Although our TDS was low when we first started the system, and although "Grow Big" is an organic product, I was initially reluctant to add the product to the water with the fish. While the students were out for spring break, we wouldn't have access to take care of the fish. We ended up taking the fish to our office for a vacation, and I tested out the fertilizer in the system before the break. After the break the plants looked great. </p>
<p>Come to find out, we had missed a fish who was doing really well despite going hungry for a week and living in the dark in water that had fertilizer. Ever since then, I've added an ounce of fertilizer every time the TDS drops below 200. But I would never apply more often than once every two weeks.</p>
<p></p>
<p>I'm really not sure what to do at this point. The fish seem ok, but the plants are really starting to get stressed out by the high pH.

<p>Hi Everyone,</p>
<p> </p>
<p>I live in Austin, TX, and my tank ranges from 74degrees in the morning to 91degrees in mid-afternoon. I don't see fish adapting well to this range at all. It is a glass tank that sits above ground, and it is in shade all day. I plan on putting some shade netting around the tank anyways, to hopefully cool it down a bit more, but I don't think it will make much difference. Does anyone have any suggestions?</p>
