  • 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.

  • 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.
