<p>I insulated around my tank and it made a big difference...just used regular house insulation bats around the sides and covered the top with a tarp. I also have talapia and am super impressed by their hardiness...At first I was experiencing temperature swings of around 10 degrees also between day and night (have the tank in a greenhouse) but the insulation cut that in half...In an ideal system you want minimum temp swing within the range that Matt said...I also have a 300w heater that i…</p>

<p>Marshall,</p>
<p>The temperatrue range for Tilapias is 60-95 deg. F, optimal range is 74-80 deg. F. They are very hardy in regards to water temperature, water quality and oxygen levels.</p>
<p>To regulate the temperature and keep it at a more consistent level I would put in a heater in the tank for the cooler CO nights and also cover the tank throughout the day, (we use that blue styrofoam insulation as a makeshift cover).</p>

<p>Trout are a more advanced option for AP systems in that they need consistently cool, fast moving and highly oxygenated water. If you think about the last time you stuck a toe in a mountain stream, thats about what you would need to provide to make them happy.</p>
<p>Additionaly, the water temperatures that trout require (38-68 deg. F, optimal temp range is 55-65 deg. F) are a bit cool for the roots of most warm weather crops to thrive.</p>

<p>It's just one bed which is about 90 gallons with hydroton. It's pretty densely planted. No extra filtration or aeration though the return feed looks like it provides a lot...</p>
<p>Mostly I'm worried that the temperature swings between 66 and 78 during the day. I'm going to try to get some insulation but I don't know how much good it will do. It might also do better when the kelp finishes clearing up. I just heard that tilapia were sensitive to temperature fluctuations.</p>

<p>sounds like you're starting with a high stocking density.. how many gallons of growbed/media? do you have any extra filtration? any aeration?</p>
<p> </p>
<p>I started 50 1" tilapia in a single tote system but moved them to the pool after they were 3-4".. if your tote is cut in half (half gb half ft) i'd only stock 15 tilapia to grow out (and i wouldn't grow them much beyone 1lb) in the first year..</p>
