Natural Chemistry Spa Calcium Increaser – 1.83 LBS
$19.95
Most of Western Washington has very soft water that is damaging for spa parts like pump seals and hot tub heaters. Our soft water is great for drinking, but hard on metal and ceramic parts. Natural Chemistry’s Spa Calcium Hardness Increaser is used to raise calcium hardness in hot tub water. Unless you’re using the ACE Saltwater system or SilkBalance in your hot tub, your hot tub’s calcium hardness should be maintained between 150-250 ppm. Maintaining the proper calcium level not only protects your equipment, it keeps sanitizers working for a longer period.
- Boosts calcium levels in soft water
