Looked at the site, can't see anywhere that tells me what Kleen Pool actually is--but I will tell you that if you maintain adequate chlorine levels, you won't have algae. The only algaecide we recommend here is Polyquat 60, usually in cases where the pools are being closed for the winter, metals are present in the water, etc...but in the vast majority of cases, if you'll just keep your chlorine where it needs to be, you don't need to add any other algae preventative.
