Balanced water is neither too alkaline (high TA/pH) which causes scale buildup, nor too acidic (low pH) which causes damage to spa pumps, seals and heaters. Proper calcium hardness prevents corrosion and reduces water foaming.
- Alkalinity & pH Up 1 lb.
- Alkalinity & pH Down 1.5 lb.
- Calcium Hardness Booster 14 oz.
Product notes: Check spa water with test strips. Adjust Total Alkalinity (TA) first, then adjust for proper pH range. Proper TA will buffer pH, preventing fluctuations.
