Deep Blue Spas Calcium Hardness Increaser - Calcium Chloride Flakes

Calcium chloride dihydrate flakes give pool and spa engineers a practical way to correct low calcium hardness across routine service work. Dealers can order Deep Blue Spas retail packs in 1kg, 2.5kg, 5kg, 10kg, 20kg and 25kg sizes, covering anything from counter sales to larger maintenance accounts. The flakes dissolve quickly and contribute calcium directly to the hardness reading. Retail-ready presentation with compliant labelling makes this a straightforward core line for resellers serving installers, contractors and water-care businesses.
