pH Down 3kg – Store pick up ONLY
Chemical Type: pH Decreaser
Chemical Base: Sodium Bisulphate
pH Down (decreaser) is a dry acid that is safe to handle and store. The recommended range for pH in swimming pool and spa water is 7.2 – 7.8. When the reading is below 7.2 the water is acidic and above 7.8 the water is alkaline. Alkaline water can cause scaling on all surfaces and leave the water cloudy. When left untreated for long periods, this can cause a build-up on the pool surface and in the pipes, which can affect water flow, and put pressure on the filtration equipment. Chlorine is most effective at controlling bacteria and algae when the pH level is within the recommended range. This also saves on chlorine usage.
For cloudy pools, we recommend treating the water first. Once the pH is balanced, using pH up or pH down, and any algae have been treated with algaecide, then we suggest you use a flocculant to clear any suspended matter.
Dosage: Rate will depend on the pH and Total Alkalinity level. Check the label or consult your local Pool Professional
