<p>Looks cool, but how do you maintain a healthy diet for edible fish in an ecosystem like condition? I'm not a fish expert but, I'm not sure algae is sufficient for most fish--except secondary consumers. Is there any supplemental energy added to the system when the fish have a lower growth rate. Also, would this be extremely low stocking densities. </p>

<p>One more question about some language in your post, "Take any level, the energy consumed by animals has to be absorbed by the animal or exited out the back end. The majority of the energy is still contained in the “back end” energy waste or poop. If only 10% of the energy is consumed by the animal, 90% of it goes out the back.". Um... how I learned the 10% rule in biology was that 90% of the energy was used by each trophic level--not exited as waste. But, it's probably how I read this. Or my knowledge is a bit incomplete. Anyways that post was cool and I look forward to more.<img src="http://www.bkserv.net/images/Grin.gif"/><br/> <br/>

<p>Hi Miguel, <br/>I have an AP system where I have not feed fish for a year. They eat the algae off the walls of the tank. I made a video how to start one. Here are some responses to topics 1, 2 and 3. <br/><br/>1) No, do not put manure directly into the system. It will change your pH by adding anaerobic bacteria which produce acids. If you want to use poops, compost it in a worm compost until all gone, not a traditional hot and/or cold compost, extract it into the water and the nutrition will be available for the plants. <br/>2) I use red and green algae. I start with well competed soil compost and then extract it using a 400 um bag, Both algae will appear. <br/>3) And yes, it is possible to design a system with no feeding.</p>

<p>1. I suppose indirectly adding the nutrients to the system, such as making a aged manure tea and feeding it to duckweed and algae is possible, (I've not tried this so, I would ask someone else about it) then feeding the food to the fish thus integrating land based gardening to soil-less gardening. </p>
