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

we like these HTH brand for chemicals and they work best for us. we use the shock, stabilizer, and3-in pool tablets by HTH. the pH has to be right before you can add the shock or you will waste a lot of shock. at the beginning of each year we also stabilize our pool as soon the chemicals arevin the right range which is necessary. I personally desolve the shock in pool water by stirring it with a plastic paint stirring tool. I put a little and a bucket at a time and throw the water toward the center of the pool and some around the edges. it works well for us that way and we don't have a lot of residue everywhere. be sure to use your pool water and not faucet water so it has the same chemical levels as your pool water. that's just my theory. we vacuum next day.

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!
