pH Down 500g
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 spa and swimming pool 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 build-up on the pool surface and in the pipes, and can affect water flow, which can then put pressure on the filtration equipment. Chlorine is most effective at controlling bacteria and algae when pH level is within the recommended range. This also saves on chlorine usage.
Dosage: Rate will depend on the pH and Total Alkalinity level. Check label or consult your local Pool Professional
