    • Great Algae Kill.
Style: Ultra Algaecide
Greatest stuff on planet earth! Clear, Clean Water! It was cloudy all summer, if there’s white algae, couldn’t get rid of it, end of summer found this and dumped 2 bottles into the pool and crystal clear! Bought more and am ready for this summer!

    • Worked Well
Style: Advanced Algaecide
I have a 35,000 gallon pool and had green algae forming in several places. This knocked it out in less than 36 hours. It did foam for a few days but may be that I added too much. I would definitely buy this again for algae.

    • Product worked great!
Style: Advanced Algaecide
Crystal blue pool but noticed a few stubborn black algae spots show up. Tried a couple different products with no results. Algae got worse. Had to use the whole bottle, two different treatments a couple days apart but it worked perfectly. Now I can finish getting the pool swim ready.

    • Concentrated and works well.
Style: Advanced Algaecide
Although the price would seem to be high the reality is it is concentrated and you need a lot less as compared to other algaecide products that are typically sold in the gallon size. This is a better buy and works well.
