I was doing some research into the CYA test and learned that melamine is used to precipitate the CYA and the turbidity produced is used to estimate the amount of CYA. It occurs to me that melamine might be effective in removing or reducing the CYA levels in a pool. That would avoid having to drain and refill when the CYA gets too high. Has anyone tried this? Is there some reason it cannot or should not be done?
