About Spa Essentials 32534000 Calcium Hardness Increaser Granules for Spas and Hot Tubs
Overall Feedback:
69% positive
76% liked its ability to stabilize alkalinity levels, but 24% experienced sudden changes.
To bring my 250 gallon hot tub to normal range, it takes almost a whole bottle of calcium hardness.
