Pool balancing

The recommended water chemistry balance in pools with ceramic tile finishes is as follows:

> Total alkalinity range recommended: 80 -200 mg/l

> pH range: 7.2–7.8

> Calcium Hardness range: 150 -200 m/L

> Sulphate range: <200 mg/L

While these values may be slightly different to what many operators would regard as normal, we emphasise that these values are related to ceramic tile finishes that have been fixed (adhered) and grouted with cement based products. The values given here are in the recommended ranges to prevent corrosion of the cement in the adhesives and grouts.

Normal recommendation for acid cleaning of tile and stones with HCL + water dilution is 5:95.
