Re: Seapool?
Copper sulfate shows up in many "non chlorine" sanitation systems.
1. It is not an EPA approved residual sanitizer.
2. It is very slow acting and a pool requires a sanitizer with fast kill times.
3. Copper is an efficient algaecide so the water doesn't turn green from algae so one is lead into the false assumption that clear water is sanitized water. It is not.
4. Copper is what turns hair green and stains pool surfaces. Period.
5. Copper sulfate is dirt cheap so companies that sell this garbage make a LOT of money.
