Pool Plus- Water Hardener

Aquachem Pool Plus Water Hardener

Protect your pool surfaces, equipment, and water balance with Aquachem Pool Plus Water Hardener — a straightforward, effective calcium hardness increaser formulated to raise and maintain the calcium hardness level of your pool water within the ideal range for safe, balanced, and equipment-friendly pool operation. An essential component of comprehensive pool water management, proper calcium hardness is one of the most important yet frequently overlooked aspects of keeping your pool water truly balanced and your pool infrastructure protected for the long term.

Water that is too soft — with insufficient calcium hardness — becomes corrosive and will actively seek to draw calcium from wherever it can find it, including your pool's plaster, grout, tiling, and equipment surfaces. The resulting etching, pitting, and surface deterioration can cause significant and costly damage over time. Aquachem Pool Plus Water Hardener corrects low calcium hardness quickly and reliably, establishing the protective mineral balance your pool water needs to remain stable, comfortable to swim in, and kind to your pool's surfaces and equipment.

Key Features:

• Fast-dissolving calcium hardness increaser that rapidly raises pool water calcium hardness levels to within the recommended range for balanced, stable, and non-corrosive pool water
• Protects pool surfaces from the etching, pitting, and erosion caused by soft, calcium-deficient water that aggressively draws minerals from plaster, grout, tiles, and pool finishes
• Safeguards pool equipment including pumps, heaters, heat exchangers, and salt chlorinator cells from the corrosive effects of chronically soft, unbalanced pool water
• Supports overall water balance by contributing to the Langelier Saturation Index — the key measure of whether pool water is corrosive, balanced, or scale-forming
• Suitable for all pool types including concrete, fibreglass, and vinyl liner pools across both chlorinated and salt water systems
• Simple, straightforward dosing with clear application instructions for confident, accurate water hardness correction
• Compatible with all standard pool sanitisation and chemical treatment systems without adversely affecting water clarity or sanitiser performance
• Part of the trusted Aquachem Pool Plus chemical range, formulated to Australian pool care standards for reliable, consistent water treatment results

Ideal For: Pool owners with low calcium hardness readings who need a reliable, fast-acting treatment to raise and stabilise pool water hardness levels — Aquachem Pool Plus Water Hardener is the essential corrective treatment for protecting pool surfaces, extending equipment life, and maintaining the balanced, stable water chemistry that every well-managed pool depends on.
