From the deep end of the pool, reach down to elbow length (18") and collect 8oz. of water in a sample bottle or any clean plastic container. Take this water sample directly to your authorized pool professional. They will analyze the water and tell you how to ensure proper water balance and chlorination levels in your pool.
Why balanced water is important:
Balanced water is held safely between two harmful extremes. If water falls out of balance on the low side, it becomes corrosive, attacking pool surfaces and equipment. If it should rise out of balance on the high side, scale buildup can occur leaving unsightly deposits. Out of balance water can cause skin and eye irritation, staining, cloudy water and will interfere with the sanitizer's effectiveness.
