5.0 out of 5 stars Great for killing algae
Reviewed in the United States on May 13, 2024
My pool was medium-green from algae and nothing was working to get rid of it. Since this was the first time I had ever had an algae problem, I was just fumbling around while I tried to get my water back to normal. I tried shocking with a normal amount of shock, tried algaecide, tried clarifier, but nothing worked at all. Then I read that a triple dose of shock could kill algae, so I researched better brands of shock than I had been using and decided to try Clorox. I put four bags into my 15,000-gallon pool, which equaled a triple dose. After one day, the water was a lighter green. After two days, the water was barely green. After three days, the algae was totally gone and the water was the brightest blue I've ever seen it. This stuff works great!

I add 1 bag a week and pool stay clear. I like is you do not have to pre dissolve . The 6 to 1 has Alge control and this also works great.

I have purchased some different brands and they don't seem to be as effective in my opinion. The clorox shock and chlorine do a great job keeping chlorine levels stable, long lasting and pool is ready to go when family wants to go swimming.

Cheaper than the BioGuard version I usually buy and performs pretty well. There’s more fine material, so don’t be down wind when applyin

I’ve used this pool shock for the last 2 summers. As long as I use it weekly as instructed the pool looks clear and the chemical levels are where they are supposed to be. I was about 5 days late for my weekly treatment and the pool was looking cloudy and a little green today. It will be clear and blue by tomorrow afternoon. The photo attached is a day after the shock last summer. Great value and performance for this pool shock.
