Stabilizer remedies UV-induced chlorine decrease

After undergoing a late-Spring algae bloom, I researched remedies to conquer this issue. Among those listed included cyanuric acid, which is the main component of this HTH pool stabilizer. The UV rays in my desert location apparently erode my chlorine very quickly. Since buying and applying this product, I notice that my pool has been cleaner, for longer between chlorine doses, than in the pre-application days. I will continue to order and use this product — I am now in my second bag – to ensure that my pool water remains stabilized, clean, and blue.
