I have been working on this for a couple months now.
Here are some updated photos showing the system with plumbing in place. The system is cycling right now. It is chewing through ammonia, but still waiting on the nitrites to drop. Did several water changes to at least get the nitrites on the radar. The tank with plants in it is a clarifying tank. It is filled with shade cloth. I got one heck of a deal on a large purchase of shade cloth, and needed it to cover the greenhouse, make shade shelters for livestock, and coincidentally, it should work well for filtration. The blue drum is a 70 gallon moving bed filter filled with kaldnes media. The water pump runs most of the water through the filter, and dumps primarily into the far tank, but I have outlets at each tank to dump some filtered water in. The water moves tank to tank by the U tube siphons. Some of the water is diverted before the moving bed filter, and flows into the grow beds. The grow beds have a bell siphon, which makes for an automatic fill and drain cycle. Plants will be grown in the grow beds, and should remove most of the nitrate, and minimize water changes. Two of these heat coils

I am quite proud of it so far, and am dying to get it completed and stocked. There is also a blurry photo of some tilapia fry. Let me know what you guys think.
