## Questions & Answers

**Q: Thank you, My pool was clear before I put this in. that stuff doesn't dissolve. Have to use clarifier after using this product?**
A: Dump into a bucket of water from pool and dissolve then walk around pool adding the contents of bucket into your pool, if you stir the shock in bucket for a few minutes it dissolves.

**Q: Can i use it for salt system? i heard we cant shock salt pools with calcium products**
A: It is recommended you dissolve the shock in a bucket of water first, this product is very good when opening pool, green water. The salt System will not clear the water by It self.

**Q: Is the sale price for 12 packs of the 1 lb shock, 6 packs or just each 1 lb item?**
A: You receive 12 one pound packs.

**Q: Is this good for vinyl pools?**
A: Use Leslie's Chlor-Brite for long term pool maintenance. Pow Pow is strong enough to kill algae, but may ruin vinyl pools. You may use Pow Pow a few times a year for vinyl pool, but it is not recommended as it may ruin the vinyl lining. If you do use it, brush it around until it dissolves. I service pools for a living.
