Hey guys, sorry if this has been covered, but I can't find it.

Has anyone thought about recycling water from a fish tank to water the peppers or even seedlings ready for a little fertilizer? I've got a twenty gallon fish tank that I change out about half of the water every two weeks. It's a lot of water being poured down the drain. The ugly chemicals assoc with tap water have been dealt with to make it safe for the fish. Nitrites and ammonia are dealt with by the bacterial flora intrinsic to a fishy micro-ecosystem. Not to mention, the water is full of organics from the critters swimming around in there. My fish are about due for a water change, but I'm afraid to try it until I know it's not toxic to the plants and more importantly to the people who eat the pods.

If anybody has any ideas or information about this, I'd be very grateful.
 
here ya go mate this is my setup

P.S no chemicals are used whatsoever, i salt the tanks to help with the fishs slime coat as a proventative measure to insure fish stay healthy, the whole system is running 24/7 no discarding of water needed as the plants eat up the nitrate
 
mine are mostly swordfish, platys and the like. nothing worth eating, but Its good to know it works. Not to mention the idea of moving to a setup large enough to put the whole meal on the plate with the big fish they've got. IT might take me a couple years to convince the wife to let me invest, but that would definitely be cool.

Thanks for the help.
 
I've been using water from a plastic tub with about a dozen crawfish for irrigating some fruit trees and brewing aerated compost teas. I draw off (and replace) about 5 gallons every couple of days. It's a new experiment, so if I'm still alive after eating my first harvest, that will provide some evidence of its safety. Nice thing about crawfish is that I don't have to worry about treating the tap water before pouring it in, because they're pretty hard to kill.
