Rx Clear 7% Copper Algaecide | Kills and Prevents Algae for In-Ground and Above Ground Swimming Pools | Safe Formula for Swimmers | One Quart Bottles | 2 Pack

Great product. Would definitely recommend. We had some algae growing on the sides of our pool. I'd brush it off, but within a few days it would come back. A pool guy said we had "mustard algae" and we needed a copper algecide to get rid of it. This was about half the cost of a similar item that I could have purchased at our local pool supply store.Bottom line - this stuff worked great. In just a few weeks, it completely eliminated the algae problems and the sides of our pool are nice and clean now. I will continue to follow the recommended maintenance dosage and expect our pool to stay beautiful for a long time.

Cleared my cloudy pool up within 24 hours.

Simple & affordable way to boost pool copper.

Product was fine they shipped UPS super slow over a week later than originally promised!

Copper algaecide works well in our pool. Just be careful not to put too much in.

It works

My pool has never looked better. I have recommended this to friends and family. Has cut chlorine demand dramatically.

I was recommended to use a copper cleaner to get the algae off my pool ladder. It did not work. The product also left stains at the bottom. Luckily after several days the stains disappeared.
