SpaPureAlkalinity Increaser 16oz

arrived quickly and accurate. well packed unlike some previous vendors I tried, good value for 3 bottles.

Good stuff

Cheaper than the pool store and delivered.

works well

Will be used in pool when alkalin level needs ti be raised.

Works as promised in the hot tub

Nothing special to write. It does what it's supposed to do.

This was already used. A quarter of it was gone and used. No seal ! So I only had 3 quarters of a bottle left. I just put it in my hot tub so hopefully it’s the correct product going in since it was already opened. Guess we’ll see. Price is very good but just wish it wasn’t used.
