I wrote a couple of blog posts describing how I built my indoor Aquaponic system, and thought some of you might be interested in reading:http://www.whatisaquaponics.co/how-to-build-an-indoor-aquaponic-sys...
This is part one. Part 2 will be up tomorrow.
If you have any questions, please ask. I'll try to pass along the things I have picked up from fellow aquapons!
Thanks Jon - my outdoor system pumps from a sump tank, and feeds the grow beds from the fish tank - because I am aware of the dangers of pumping from the fish tank. A couple of times my sump tank has been pumped dry, so this is a very real consideration. Since this system is inside, if I have any leaks - the water in the fish tank is my least concern! However, with the grow bed directly above the fish tank, draining directly back down into the fish tank, any small leaks are likely to be caught by the fish tank anyway.
I had not considered how pumping clean water would be beneficial to the pump, so I'll keep this in mind.
Not sure if these are the same catfish called by a different name, but the fish in this tank are Iridescent Sharks (a tropical catfish?) that came with the tank. They may be edible, but I'm not sure I could tell my friends that gave me the tank that I ate them ;-) Eventually, I would like to get rid of these and use this tank for fingerlings before transferring the fingerlings to my outdoor system.
