    • Great value for my hot tub
Size: No Size Style: pH Down
Bought this as part of my overall spa care routine. Helps keep the water clear and my pH level in check. So far it’s functioning as I would expects. Dissolves quickly while the jets are running with no obnoxious smell. Will buy again when I run out.

    • Works fine
Size: No Size Style: pH Down
Happy with it. I believe I picked out of desperation and best priced. Strong smell, but I slightly think it smells good. Really, just not used to that because I normally used a liquid version from a store brand. Does what it says. However, I feel I had to use more than I would if in liquid form. Hard to judge though since different brand and scenario levels vary. I’d buy it again if needed, but I still prefer liquid (as seems stronger), as to not increase total dissolved solids in the water ... show more

    • Just what I needed
Size: No Size Style: pH Down
I purchased this for my inflatable hot tub. I noticed my ph was way too high, so I needed to purchase this to bring down my ph level to normal levels. I had it back in normal range in no time. I will absolutely purchase this again.
