3 Things to Know About Using Pool Shock and Algaecide

Never add shock and algaecide at the same time The chlorine in shock will break down most algaecides before they can work, wasting your money.

Shock first, then wait before adding algaecide Add shock, let chlorine levels drop to normal (usually 24-48 hours), then add algaecide so each chemical works properly.

You probably don’t need algaecide at all If you maintain proper chlorine levels, algaecide is unnecessary. Most green pools just need a good shock and filtration.
