Good product to keep my tub clean
Bought this clarifier to use in my overall spa care routine. Large bottle makes it a good value for the money. Has been functioning as well as any other products I’ve used with no obnoxious smell. Keeps my water crystal clear. Will buy again when I run out.

Great product!
This stuff worked miracles. Hot tub was chemically balanced but I could not clear the haze. I tried another clarifier and the water did not clear. This worked within 4 hours.

Sparkling water
This spa clarifier cleared up my cloudy hot tub water within hours although chemicals were balanced. Super easy to use—just pour 1-2 capfuls in. No foam, no smell, and it didn’t mess with water chemistry. We use it about once a week now for clear water

Best $10 I Ever Spent
Finally a product that does what it promises. I drained/refilled spa two weeks ago and it clouded up a few days later. Ph and Chlorine were fine. Tried to shock with Renew to no avail. Put 4oz of this in my 500 gal spa and overnight milky, cloudy water turned clear. Best $10 I ever spent.

The package arrived, l opened it and the bottle had no cap on it. All it had was the cardboard seal which was starting to leak on prior to arrival. Obviously no quality control. Not sure if it works yet but still not impressed.
