I heard the shit from the fresh water fish would feed the plants if u put some water from the tank. I have frogs and guppies. The frogs eat blood worms and the guppies eat flake food. Would any of those stuff will be bad to water my plants? I also have a filter thing for it.

well hell. . . maybe it does work but it seems a little sketchy to me. . . seems like you'd have a hard time controling and measuring the amount of beneficial bacteria and nutes in the tank water. . . Shit if you use the tank water for your grow, keep us posted on the results! good luck my friend!

naturally occurring beneficial bacteria convert the ammonia and waste to nitrites, then into nitrates which the plant use, so its just organically nitrogen enriched water.

It will not hurt WHATSOEVER. I have watered my vegetable garden with my koi pond water for a year, they LOVE IT. I have also tested aquaponics rigs with various plants, great results (mainly in veg.) I am yet to test it on my Cannabis since I already have plenty of quality organic nutes to chose from and time is money, BUT I certainly don't ever see it hurting.

That is unless your fish tank is totally disgusting and filled with insect larvae etc. If it's healthy and clear, GO FOR IT.

aquaponics is the shits. But i've noticed that using a biofilter first before feeding it to your plants works best. Simply brew the fish tank water in a separate container to make sure all the nitrites form to nitrates first. The bacteria is already in there and they will break down the nitrites into nitrates in the soil, but doing it in a separate reservoir seems to be what most aquaponic people do.
