ClearwaterCH0008 PH Minus Decreaser for Swimming Pool and Spa Treatment

Not the first thing on your list to buy when you get a tub, but definitely something that will make you feel a bit more comfortable if you have it in your cupboard

Product is OK but the lid doesn't fit properly so when I first picked it up the lid came off and the powder spilt all over the floor.

Excellent product. Does what it says and fast delivery. Highly recommend!!!!

Arrived quickly and is super easy to work out how much you need with the table on the back, provided you use the pool strips beforehand that is

Will do what I need for my hot tub at a good price I think for a proven good quality.
