In The Swim Pool Calcium Hardness Increaser
In the Swim Pool Calcium Hardness Increaser effectively resolves low hardness levels, preventing aggressive water behavior. When levels fall below 200 ppm, water extracts minerals from surfaces, causing etching and corrosion. Add the Increaser to raise levels to the ideal 200 - 400 ppm range. Contains 97% granular calcium chloride. Dosage: 6 lbs. per 10,000 gallons raises levels approx. 50 ppm. Do not premix or mix with small amounts of water, as it undergoes a chemical reaction generating heat.

Signs of Low Calcium Hardness
Low nutrient levels make water aggressive and corrosive, causing it to leach minerals from surfaces, leading to etching and equipment corrosion.
Adjusting and Balancing
Regularly test pool/spa water to maintain optimal chemistry, promoting a healthy environment, saving cost, and reduce pool maintenance.
Sanitizing
Keep water clean using trichlor tablets, along with shock and granular chlorine for maintenance, for a sparkling clean pool.
Treatment
Pool not looking perfect, begin by testing the water. Address specific issues such as algae, cloudiness, debris, or other conditions with needed chemcials.
Pool Safety
Ensure a safe aquatic environment with essential safety equipment, knowledge of local regulations and pool supervision
