HTH Super Clarifier

Works great - keeps my spa water crystal clear

I don't know what magic this is, but if I put it in my pool either in the morning, or in the evening and let the pump run overnight it make the water fully clear. I usually use it after shocking the pool. I think the chlorine kills the algae that makes a green tint and then this stuff clears out the dead algae. In any case, just a few ounces poured in the pool and it makes the water clear! You can get so many uses out of one bottle and it is very reasonably priced. I would suggest using this anytime your pool gets a green tint to it, it is magical and well worth whatever it is priced. I could not recommend this product more! I have bought it multiple times!

Works good

Just a tablespoon and my hot tub is looking great again. It's super thick, but works very well.

The only pool clarifier I will ever use again! My pool has stayed sparkling clear the entire hot summer. I’ve never had this much luck before.
