WHY CALCIUM HARDNESS MATTERS
Unbalanced water isn’t always visible—but its effects can be long-lasting and costly. When your pool’s calcium hardness is too low, the water becomes aggressive, pulling minerals from any available source to rebalance itself. This results in a range of serious issues including etching on plaster, pitted tile grout, weakened plumbing seals, and internal corrosion in heaters and filters. Pool Supplies Canada’s Calcium Plus offers a powerful, proactive solution to prevent these hidden threats and keep your water chemistry in check.

HIGH-PURITY CALCIUM CHLORIDE FORMULA
Calcium Plus is formulated with high-grade calcium chloride made specifically for pools and spas. This 7 kilogram container delivers a fast-dissolving, evenly dispersing treatment that raises calcium hardness levels to the recommended range—typically 200–400 ppm. No pre-mixing is required; just sprinkle it directly into the water and let your filtration system do the rest.

- Raises calcium hardness safely and efficiently
- Prevents aggressive water from damaging pool surfaces and plumbing
- Dissolves quickly for fast, even distribution
- No pre-mixing or complicated application needed

PROTECTS YOUR ENTIRE POOL SYSTEM
Low calcium levels can silently degrade the structural integrity of your pool. From surface wear to internal corrosion, the damage can add up quickly if left unaddressed. Regular use of Calcium Plus helps safeguard your pool against this silent deterioration while also improving the performance and longevity of your equipment.

- Protects heaters, pumps, and plumbing from internal corrosion
- Helps extend the life of filters, liners, and circulation components

SUPPORTS OVERALL WATER BALANCE
Calcium hardness is one of the three pillars of balanced pool water—alongside pH and total alkalinity. Restoring and maintaining proper calcium levels helps support the performance of your sanitizers and stabilizes the water chemistry as a whole. This means better clarity, more effective disinfection, and less chemical waste.

- Enhances chlorine and bromine effectiveness
- Helps maintain consistent pH and alkalinity levels
- Supports clearer, more comfortable water year-round
- Reduces maintenance time and chemical costs over time
