Pool DC Calcium Flakes | Calcium Hardness Increaser | 4kg | For Newly Plastered Pools Powder Drum Outdoor Contact Cement  (4 kg)

Protect your new pool plaster with Pool DC Calcium Flakes. After re-marbeliting, pool water is often low in calcium hardness, which can cause the water to draw calcium from the fresh plaster — leading to etching, pitting and a shortened plaster lifespan. Adding calcium flakes raises the calcium hardness level in your pool water, preventing damage to newly plastered surfaces. This 4kg tub dissolves quickly and helps balance your water chemistry for a long-lasting, smooth finish. Features: Raises calcium hardness in pool water Protects new marbelite and plaster finishes Prevents etching and pitting Fast-dissolving flakes 4kg tub When to use: After re-marbeliting or re-plastering your pool When calcium hardness levels are low As part of regular pool water balancing Application: Test your pool water for calcium hardness. Add flakes according to your pool volume to reach the recommended level (typically 200–400 ppm). Pre-dissolve in a bucket of pool water before adding to the pool for best results.
