About this item
- ✅RAISES CALCIUM HARDNESS TO IDEAL LEVELS: Low calcium hardness can silently damage your pool. This 7 kg formula increases calcium to the recommended range, helping you maintain water balance and avoid costly surface or equipment repairs down the road
- ✅PREVENTS CORROSION AND ETCHING DAMAGE: When water lacks calcium, it pulls minerals from grout, tile, and metal parts—causing pitting, scaling, and deterioration. Calcium Plus adds essential hardness to protect your pool’s finish, plumbing, and heating components
- ✅ENSURES LONGER EQUIPMENT LIFESPAN: From your pool liner to your heater and filter system, this formula helps safeguard everything your water touches. The right calcium level acts as a shield, defending against internal scaling, corrosion, and chemical inefficiencies
- ✅FAST-ACTING, HIGH-PURITY CALCIUM CHLORIDE: Made with premium-grade calcium chloride, this granular formula dissolves quickly and circulates evenly. Just test, measure, and apply directly—no pre-mixing required. Designed for precision and ease in every application
- ✅IDEAL FOR ALL POOLS AND SPAS: Whether you own a saltwater, chlorine, or bromine system, this hardness increaser is compatible with all pool types. It’s especially beneficial for soft water regions or after filling your pool with low-mineral water sources

Product description
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.
- Prevents etching and pitting on plaster and grout
- Reduces the risk of cloudy water caused by mineral imbalance
- 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
IDEAL FOR POOLS AND SPAS OF ALL SIZES
Whether you're refilling a large in-ground pool with soft tap water or managing a spa affected by frequent dilution or rainwater, Calcium Plus is the perfect addition to your maintenance routine. It’s safe for all pool types and surfaces, including vinyl, concrete, fiberglass, and saltwater systems.
- Suitable for in-ground and above-ground pools
- Works in spas, hot tubs, and saltwater systems
- Especially important after heavy rainfall, dilution, or reverse osmosis
- Helps maintain water balance in regions with naturally soft water
PROTECT YOUR INVESTMENT WITH EASE
Pool Supplies Canada’s Calcium Plus gives you an easy and effective way to prevent invisible damage and preserve the beauty and performance of your pool. With each application, you're extending the life of your pool, improving your water quality, and reducing long-term repair costs. Don’t let low calcium levels silently destroy your investment—take control with a proven solution trusted by pool professionals nationwide.
- Maintains water clarity and surface integrity

Important information
Directions
1. Test the dureté totale with un kit de test fiable. 2. La plage souhaitée pour la dureté totale est de 225 à 300 ppm pour les piscines en plâtre et de 175 à 250 ppm pour les piscines en fibre de verre, vinyle ou peintes. 3. Si la dureté totale est inférieure à cette plage souhaitée, ajoutez 112 g de Calcium Plus pour 10 000 L pour augmenter la dureté totale de 10 ppm. 4. Suivez les étiquettes sur la bouteille pour vous assurer que la chimie de l'eau est maintenue. 5. Lire l'étiquette avant utilisation : ajustez les faibles niveaux de calcium pour éviter la corrosion et les piqûres de surface de la piscine.
