Good Point Tlranger - the chemicals used in most aquaponics are crazy! I have always kept several tanks- exotic fish, simple little goldfish and a huge tank for growing bog plants. I started reading about aeroponics a few months ago and thought it was funny they were putting the fish in with the plants- I have grown all kinds of plants in my aquariums with the fish and have almost 100% success rate with cuttings in aquariums - when the fish nibble at the roots it's time to plant em!
