Does anyone have experience using copper sulfate for algae together with chelated for weeds? I have been using chelated for both, but cost-wise it would be better to use CuSO4 for algae. Anyone control weeds with CuSO4? can you get the rate high enough without killing fish? Do CuSO4 and Chelated behave themselves when mixed? i've been researching quite a bit and can't find a whole lot on it...
