PH Decreaser Dry Acid Refill 3KG

Product Description

A 3 kg refill pack of pH Decreaser (dry acid) by Hy‑Clor is designed to safely and effectively lower the pH of swimming pool or spa water. This granulated dry acid helps correct high pH levels, improving water clarity, protecting pool surfaces and equipment, and enhancing sanitizer effectiveness. Ideal for regular maintenance or when water becomes too alkaline, this refill pack gives enough chemical to treat medium‑to‑large pools.

Product Details

• Product Type: Dry acid / pH Decreaser refill (3 kg hard pack)

• Active Ingredient: Sodium bisulphate 

•  Purpose / Function: Lowers pH and helps reduce high alkalinity; brings water chemistry back to optimal pH range (around 7.2–7.6) so chlorine works better, and scaling is reduced.

• Suitable For: All pool types (chlorine pools, salt‑water pools, spas). Ideal when pH is above recommended.

• Usage / Dosage:
  • The amount needed depends on pool water volume and how far the pH is from target
  • Use small incremental doses — dissolve in a bucket of water first, distribute evenly around pool, run filtration, retest after a few hours
  • Always follow product label instructions for safety

• Packaging: 3 kg refill pack (hard pack/container) for storage convenience.

• Handling / Safety:
  • Wear protective gloves and eyewear when handling dry acid
  • Avoid inhaling dust
  • Store in dry, cool place, sealed container, out of reach of children
  • Keep away from incompatible chemicals (like bleach) until fully diluted

• Benefits:
  • Restores correct water balance, preventing cloudy water, scaling and skin/eye irritation
  • Enhances chlorine efficacy so disinfecting works better
  • Safer and easier to store than strong liquid acids (less risk of splashes).

• Limitations / Precautions:
  • Direct contact with pool surfaces (especially vinyl, fiberglass) may cause damage if undiluted
  • Overuse can drive pH too low, which can corrode metal fittings or irritate swimmers
  • Must dissolve fully and distribute evenly; filtration running helps.
