HTH Pool Care Shock Advanced — Granules, 12 Pack (1 lb each) — Pool Shock Treatment for Weekly Pool Sanitizing

I bought this HTH brand after seeing great reviews on multiple pool care sites. Walmart online purchase and pick up was by far the best price. I was very pleased with this shock. Does really well for us. Crystal clear pool. I followed the directions and mixed in a bucket to add it as a dilution solution. I preferred to add over time into the return stream over 5-7 minutes. If done slowly it disappears almost immediately. Works on my 24 round above ground.

Walmart's pool supplies are consistently less expensive than other sources and HTH Pool Care Shock Advanced is a perfect example. I've used HTH products for years and have never had any issues. The Pool Care Shock is something I use all the time. I live in FL and between heavy summer rain and the heat and sun, it doesn't take much to throw your pool chemicals out of whack. I use HTH shock (and other HTH products) to keep my pool crystal clear and safe!
