If the problem persists, consider consulting a professional technician for further diagnosis.

The time it takes to fill a 30,000-gallon in-ground pool depends on the flow rate of your water source. For example, if you use a standard garden hose that delivers about 10 gallons per minute, it would take approximately 50 hours to fill the pool. If you have a higher flow rate, such as from a fire hydrant or a dedicated water source providing 20 gallons per minute, it would take about 25 hours. Always ensure to check local regulations when using high-capacity water sources.

Alkalinity levels in a swimming pool refer to the concentration of alkaline substances, primarily bicarbonates, in the water. It acts as a buffer, helping to stabilize pH levels and prevent rapid changes, which can lead to water chemistry issues. Ideal total alkalinity levels typically range from 80 to 120 parts per million (ppm). Maintaining balanced alkalinity is crucial for swimmer comfort, equipment longevity, and effective sanitization.

Algonac Pool in Michigan typically opens around Memorial Day weekend and remains open through the summer season, depending on weather conditions.
