Review: Very happy - Works well. Used when we first opened the pool and throughout the summer. Our water quality was very good.
Review: It really works!! - It makes the water sooo soft it feels like silk gliding across your skin. Aahh....It cleared up the green tinge in my pool water in less than 30 minutes. AMAZING!! The only thing is it's quite expensive, $65 for a 6pk compared to $69 for a 12pk of my regular shock treatment so I will only use this occasionally to prevent the green tinge and when people are coming over to swim. I'll use my regular shock the rest of the time.

## Questions & Answers

**Q: What is the difference in the 7 in 1 verses the all-in-one?**
A: From the labels, it appears that the 7 in 1 has a clarifier, and prevents scale formation. They both kill algae and bacteria. Those are the only differences I could find. I may have missed something. Hope this helps!

**Q: Does the instructions say How soon after adding is it safe to swim?**
A: Google search: “In general, after shocking a pool, no one should swim in the pool for a minimum of 6 hours and up to 24 hours. This time can vary depending on the type of shock.”

**Q: should this be used alone or can I mix with hth ultimate 6 in 1 tablet?**
A: Hello, we are the manufacture of HTH Ultimate Shock Treatment. This can be used in a pool where HTH Ultimate Tablets are being used, however you should never allow the 2 products to come in physical contact with each other.

**Q: Does it contain Cyanuric  Acid?**
A: Hello, we are the manufacture of HTH® Ultimate Shock Treatment. No, this shock product does not contain CYA.

### ⭐⭐⭐⭐⭐ Green to blue overnight
*by J***N on July 23, 2021*

After 2 weeks of fighting algae, using Leslie's pool shock, and constantly trying to figure out how to at least see the bottom. This just made the water perfect. $35 for 6 lbs too. Now, I'm not embarrassed of the gross look and able to use it again, I can use the recommended amount weekly and while not having to spend a fortune and time. Edit: seeing a lot of negative reviews. You absolutely have to balance your alkalinity and PH first before adding any pool shock for any brand. This is my first full season owning a pool and my green water was gone over night after giving time for the baking soda to mix in for a few hours and then shocked the pool overnight. Also, don't pour the shock in directly. Mix it with warm water in a bucket and pour it around the pool that way. I'm confident I won't have green water again with this very simple weekly maintenance
