    • 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.
