The purpose of this chemical is to increase your spas filtering efficiency by coagulating particles that are small enough to pass through your filter. It will also help you quickly eliminate cloudiness in your spa water.
I use this every other week. Keeps water clear.
Great., love the customer service.
This is a lifesaver for our spa! Almost instantly clears up our water and has it looking perfect!
Product is ok
It works with spa shock but alone never saw a difference
