Its pricy but lasts a long time!

Works great! The pool stays algae free for months after each application. Drop this thing in your pump pre-filter and let it do its thing. Turns your pools filter an interesting color for a while don't worry about it.

Black Algae Gone!!

We had a really bad black algae issue. We put this in and within a week all of it was gone. Been using for over a year now and never hardly even have to put in chlorine.

Love Pool Rx!

I order one of these every year, and the pool looks clear all summer. It works better than anything else that I have tried.
