I would definitely shock it with liquid chlorine. YOu didn't give a CC reading, but I suspect that the problem is either that the algae bloom isn't completely dead, or your chlorine is busy fighting off the phosphate remover. (Out of curiosity, why did you add treatment for it?) Either way, your SWG is going to have problems keeping up. My advice...shock it!
