- MAINTAINS OPTIMAL CALCIUM HARDNESS: – Boosts calcium hardness in hot tub and spa water to ideal 80–200 ppm range. This calcium hardness increaser for hot tub helps protect surfaces, jets, and heaters while improving sanitizer efficiency and water clarity.
- ENHANCES EQUIPMENT DURABILITY & FUNCTION: Soft or low-calcium water can shorten spa equipment life. Our liquid calcium hardness increaser helps maintain proper mineral levels to support heaters, pumps, jets, and metallic parts in hot tubs and saltwater spas.
- REDUCES FOAM AND CLOUDINESS: – High water hardness supports cleaner, clearer spa water. This spa calcium hardness increaser helps reduce sanitizer demand, prevents hazy water, and works with chlorine, bromine, and mineral-based spa care systems.
- EASY DOSING & MAINTENANCE: – With pump running, add 1 fl oz per 500 gallons to raise calcium hardness about 10 ppm. Wait 2 hours and retest, repeating at half dose if needed. Use weekly or after draining to maintain optimal spa water hardness balance.
- RELIABLE SPA FORMULA & SYSTEM COMPATIBLE: – Designed specifically for spas and hot tubs, this calcium hardness increaser works seamlessly with chlorine, bromine, saltwater, and mineral sanitizer systems. Made without fillers for clean, effective water hardness control.
