I learned about this product from a friend who owned a pool supply business. At first I was skeptical since algae is always a problem during pool season. I started using Pool Rx 4 years ago and could not be more pleased. The minerals dispersed in the pool (a 16 x 32 in ground) totally control any algae buildup. What is really impressive is the fact that you can use a significantly lower amounts of granular chlorine and still keep the pool algae free. One unit easily lasts the entire summer. After the pool is balanced, just drop the unit into a skimmer basket and forget about it. Just follow the instructions to not backwash to give the chemicals time to fully circulate throughout the pool and the filter. I highly recommend this product.

For reasons unknown to me this is the 2nd one I had purchased & it didn't work as well as the last one. Algae still comes to visit, I'll wait until next year & try again to see if it will be as good as the first.

This little unit is easy to use and only need one per year, also available cheaper refills. I have scrubbed, put liquid algaecide and clarifier for 7 years Into my hot summer my South Florida salt water pool always fighting and never could get ahead until I bought this unit. One and done! I wish I discovered this unit sooner, will never change again. Excellent algaecide, designed for hot Florida summer, highly recommended.
