Calcium Chloride Flakes, 500g

Why Pool Water Needs Calcium

Low calcium hardness (<150 ppm) makes pool water "aggressive" or corrosive. Such water seeks to balance itself by leaching calcium from plaster, grout, tile adhesive, concrete, and even metal components like heaters and pumps.

Adding calcium chloride prevents:

· Surface etching and pitting on pool walls

· Grout and tile loosening

· Corrosion of metal equipment (heaters, pumps, pipes)

· Premature aging of pool structure

Application Guidelines

Step 1 – Test current calcium hardness with a test kit.

Step 2 – Calculate dosage:

Approx. 2.5 kg per 10,000 L (2.5 kg/10,000 L) raises hardness by ~50 ppm

Step 3 – Pre-dissolve in a plastic bucket (max 5% concentration).

Note: Exothermic reaction – solution will heat up.

Step 4 – Broadcast the solution evenly around the deep end with pump running.

Step 5 – Circulate for 24–48 hours, then retest and adjust if needed.

Important Notes

· Do not confuse with calcium hypochlorite (pool shock/chlorine sanitizer) – these are different products with different purposes.

· Keep calcium hardness below 500 ppm to avoid scaling and cloudy water.

· Store in a dry, sealed container – highly hygroscopic (absorbs moisture from air).

· Wear gloves and goggles during handling.
