Aquaponics usually creates fish for food, but I am simply looking to use the nutrients of the system, and not for eating the fish. We are talking about a period of two months. I know that fish live longer in dirty water than two months, from my own inept parenting of fish.
It's not fish good that provides nutrients, but the fishes poop. Adding fish flakes is just dirtying the water. Simply because I am not eating the fish? Does not mean that the fish aren't contributing to they system. That's ridiculous, and against the entire fundamentals of aquaponics.
