Master Clear - Hardness Up (32 oz.)
Protect your hot tub or swim spa equipment from the destructive effects of soft water with Master Clear Hardness Up. When calcium levels drop too low, water becomes corrosive, leading to stained shells, etched surfaces, and permanent damage to expensive heaters and pumps. This high-performing liquid formula rapidly raises calcium hardness to the ideal 200 to 400 ppm range. Because it comes pre-dissolved, it disperses effortlessly and absorbs instantly without leaving chalky clouds, helping you maintain perfect water balance and extend the lifespan of your spa components.
-
Prevents Corrosion: Stops low-calcium water from eating away at metal heating elements, pump seals, and plumbing.
- Pre-Dissolved Liquid Formula: Mixes into your spa water instantly with zero gritty residue or cloudiness.
- Shields Spa Surfaces: Protects the acrylic shell, jet housings, and brittle plastics from scaling and staining.
- Maximizes Equipment Life: Ensures balanced water parameters so your hot tub system runs smoothly for years to come.
