Doheny's Calcium Plus, 25 lb
Calcium Plus raises calcium hardness to prevent staining and corrosion. Low hardness levels can result in corrosion of pool surfaces and fixtures. When water hardness levels drop below 150 ppm, you need to add Calcium Plus. Calcium Plus will instantly raise calcium hardness in your pool water.
Balance Your pH Levels With Ease - Balancing your pool's pH levels has never been easier with Doheny's pH Plus, pH Minus, and Alkalinity Up! Keep your pH level between 7.2 and 7.6 ppm. Staying within that range will keep you and your pool equipment safe. On top of that, having a balanced pool will prevent scaling or cloudy water. Remember, always adjust your Alkalinity levels before adjusting your pH levels. Alkalinity acts as a buffer for your pH levels. If your Alkalinity levels are out of balance, you will never be able to get your pH properly adjusted because it will never “lock in”. By making sure that your Alkalinity level is at 80-120 PPM first, then balancing your pH, it will be more stable and less susceptible to “pH drift”. pH drift occurs when your Alkalinity is out of balance and it causes your pH level to fluctuate wildly depending on bather loads and rain.
Stabilize Your Calcium Hardness Levels - Prevent stains and corrosion with Doheny's Calcium Plus and Calcium Reducer! Our strong solutions are built to act fast and work hard so you don't have to. Don't allow your Calcium Hardness levels to fall below 200 ppm. For plaster pools, maintain a range of 225-300 ppm and for vinyl, fiberglass, and non-masonry pools maintain a range of 175-225 ppm. If you are using well water in your swimming pool, a properly balanced calcium hardness level is a must!
Increase Your Chlorine Effectiveness - Make your chlorine work more efficiently with Doheny's Stabilizer! Using our stabilizer protects your chlorine from the sun's UV rays, making your chlorine last much longer. Chlorine levels too high? Not a problem! Use Doheny's Chlorine Neutralizer to quickly lower your chlorine level to a safe range.

- Do not allow calcium hardness levels to fall below 200 ppm
- Maintain a range of 225-300 ppm for plaster pools (175-225 for vinyl, fiberglass & non-masonry pools.)
- As a general rule, use 6 lbs. of Calcium Plus per 10,000 gallons of pool water. This will boost calcium hardness levels by approximately 50 ppm.
- Add Calcium Plus directly to the pool by scattering it over a large area, allowing the filtration system to spread it throughout the pool.
