HTH Pool Care Shock Advanced — Granules, 6 Pack (6 lb total) — Pool Shock Treatment for Weekly Pool Sanitizing

I've used this shock treatment several times and it works exactly as expected. It's easy to apply, dissolves well, and helps keep the pool water clear and clean. The individual packets make it convenient to use the right amount without any guesswork. Great product that gets the job done every time.

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.
