SpaGuard Calcium Hardness Increaser

Description

SpaGuard Calcium Hardness Increaser raises calcium hardness in spa and hot tub water. The desired calcium hardness level in spa water should be 100-200 ppm (parts per million).

Low calcium hardness, below 100 ppm, could cause spa water to be corrosive which may damage spa surfaces and equipment.

SpaGuard’s Calcium Hardness Increaser enables spa owners to increase their calcium hardness with this easy to use granular formula. It boosts your calcium hardness to above the danger zone, where low levels cause extensive corrosion of plumbing, jets, fixtures, and tub surfaces. Calcium Hardness Increaser helps raise the calcium level steadily so you don’t get too much calcium and start developing scale build-up and cloudy water. The optimal calcium hardness level is 200-400 ppm, while anything below 100 ppm causes corrosion.

Balance your water to prevent problems. SpaGuard spa water balancers control scale, adjust pH and total alkalinity and correct mineral imbalances. Keeping the right balance of your spa water is necessary.

How important is pH really? Having the correct pH level in your spa is crucial to your soakers’ comfort and also protects your equipment from corrosion and scale. The ideal pH is 7.2-7.6. If the pH is too high or too low it can cause those pesky red, itchy eyes!
