Yes, you can use bore water to fill an Outback Plunge Pool, but it’s not recommended without testing and treatment first. Bore water quality varies across Australia and often contains minerals like iron, manganese and calcium that can cause staining, scale build-up and increased chemical demand if left untreated.
What Problems Can Bore Water Cause?
The most common issue is iron. When iron in bore water meets chlorine, it oxidises and causes brown or rust-coloured staining on pool surfaces and equipment. High calcium levels can also lead to white, chalky scale on walls and fittings. These issues affect all pool types, not just Outback pools.
What Should I Do Before Filling with Bore Water?
Take a sample of your bore water to your local pool shop and ask them to test for iron, copper, manganese, pH, alkalinity and calcium hardness. Based on the results, they can recommend the right treatment process, including whether a metal sequestrant or pre-filter is needed before filling.
If you regularly top up your pool with bore water, metals and minerals will accumulate over time, so ongoing water testing and treatment is important.
