Increased CYA to insane levels

You think you are saving money but you ARE NOT! These have imbalanced our pool to the point that our only option is to drain and refill. The CYA levels are 133 where they should be 20 - 50ppm. We have not had this issues in the past 3 years until this year when we changed to this brand of tablets. Highly recommend doing your research before you switch to this brand. DO NOT RECOMMEND

Great buy!

Great product - arrived very quickly. Not one piece was broken and the chlorine concentration is higher than others.
