Regal Calcium Increaser 4 lb bag
Product Overview
A proven choice for protecting plaster and concrete surfaces from the corrosive effects of soft water.
Regal Calcium Increaser contains 100.0% Calcium Chloride in a convenient 4 lb bag, designed to reliably raise calcium hardness levels. This professional-grade balancer prevents the etching and staining that occurs when pool water becomes aggressive due to low mineral content. Packaged in an eco-friendly bag that uses 70% less plastic, it is the standard specification for maintaining structural integrity in masonry pools.
Benefits & What Makes It Different
100.0% Calcium Chloride
This high-purity granular formula provides the exact concentration needed to adjust water balance without adding unwanted metals or fillers.
Surface Integrity Protection
Maintaining proper hardness prevents water from leaching calcium out of your plaster, tile grout, or concrete, which avoids costly resurfacing.
Eco-Conscious 4 LBS. Packaging
The 4 LBS. eco-bag design reduces plastic waste by 70% compared to traditional pails while remaining easy to store and handle.

Pro Tip
Always add the granules to a bucket of water first rather than pouring water onto the chemical, as Calcium Chloride generates heat when it dissolves; in regions with naturally soft water like the Pacific Northwest, keeping this on hand is essential to prevent aggressive water from ruining your finish.
Common Questions & Instructions
How much Regal Calcium Increaser should I add to my pool?
To raise your calcium hardness by 1 ppm, add 1.06 oz of Regal Calcium Increaser per 10,000 gallons of water. Always test your water first to determine your current baseline and avoid exceeding 10 lbs per 2 hours in a 10,000-gallon pool to ensure proper dissolution.
What happens if my pool's calcium hardness is too low?
When calcium levels drop below the recommended range, the water becomes aggressive and will seek minerals by etching plaster surfaces and corroding metal equipment. Use Regal Calcium Increaser 4 lb Bag as part of your regular pool care to protect your pool and keep it performing at its best.
Is this product compatible with saltwater pools?
Yes, Regal Calcium Chloride is compatible with all pool types, including saltwater systems. In fact, maintaining proper calcium levels is critical for saltwater pools to prevent the water from becoming corrosive to the salt cell's internal plates.
