Great product!! Great of Poolgeek for keeping the price right!
Have used in the past. Great product and GREAT seller. Thanks for not trying to rip people off by jumping prices for no reason like the other places.
I have been using this for years and never a hint of algae.
Found out about Pristine Blue through the spa store I purchased my hot tub. It was a New Product they were in consideration of carrying. A few weeks later I dropped by and the water in their tubs were amazingly clear (better than mine) I pride myself on perfect water balance and a clean tub or pool. Since I already have no problem with maintaining a good water balance I didn’t want to invest in all the Pristine Blue chemicals. So I did my research and found this algicide to be the key ingredient. I bought this product and the copper test. For my tub it was 1fluid oz. that’s it! It’s recommended once a month. That’s when I’ll test next. Took a couple of days to notice the difference, Other than that my water has never been clearer.
I use 1/2 bottle monthly for my above ground pool. Since I have started using Algae Shield I have not had any problems. The water is always clear. I highly recommend it!
