    • Better value than the pool store
While shock is all expensive now, for me this is the best value in trying to keep my pool clear (blue) and algae free. The outer and inner bags are easily opened with a sharp knife and the product dissolves relatively quickly and works overnight.

    • works great in the pool
I put one of these a week in my pool on Fridays right before the weekend as a supplement to my tablets and it does a good job of maintaining the water quality over the weekend.

    • Amazing Product!
We have a salt water pool. We have tried a number of products in the past to clean and keep it from turning green. We can throw two of these in the pool and within 1-2 hours our pool is crystal clear No lie. Just Amazing! We honestly don't use anything else to clean our pool beside the salt & acid for ph balancing. # products total. So It saves us so much money in the end. Glad we found this product. Thank you. ... show more

    • Works Great
I have a 14k gallon fiberglass pool - I run a robot vaccum every day, run the pump 24/7, use a skimmer sock, light brush once a week and I add one of these bags every couple of weeks.... my pool is always beautiful. I wish it was a little bit cheaper.
