Pros: Keeps our cyanunic acid level in normal range
Cons: I can't think of one!
"We have had our above ground pool in use for the past 11 years. We were always using cholorine granular on a daily basis. Last year my husband developed a skin rash every time he went in the pool so we had our water tested. Our Cyanunic Acid level was 268ppm. The norm is 30-80ppm. We were advised not to use our pool. When the level of cyanuric acid rises, the “killing power” of the free chlorine residual weakens. At above 50 ppm of cyanuric acid, the time it takes to kill bacteria in the water is much longer compared to swimming pool water without cyanuric acid. When the level of cyanuric acid builds up, the chlorine becomes increasingly less effective in keeping the water clean and problems such as high bacterial and algae growth can occur. We were advised to drain our pool and start over, which we did. We now only use the Chorine free shock daily and our levels are now in the normal range and our pool is clean. No more rashes! I would have never known that cyanunic acid would have built up in our pool so much over the years and cause bacteria. We definitely recommend using the chlorine free shock and will continue to do so."

Pros: works fast
Cons: none
"This product is the best shock I've ever purchased. I've been using it for over three seasons. You can actually see it working as it floats to the bottom."

Pros: It works
"It really works. I use it in my pool as a shock when I do not have time to use chlorine. Where it is really a excellent value is when I use it as the activator in my hot tub instead of the very expensive ThermoSpas activator."
