Sorry if I did not intend to type fish, but plants remove nutrients what minerals are extracted by fish I am not certain to what degree. I am typing blindly on my phone and didn't see the mistyped word. ididn't intend to do anything to you.
In my thread about nitrate levels I was hoping to see a pattern of this level of nitrates is best for this type of veggie/ plant and which works best with which type of fish. It's a given tilapia are best economically raised in the south or at least a state where they are legal. The rest of us will use other types of fish. This information works best to prevent newbies from failure.
