Pool water levels naturally decrease due to evaporation, splash-out, and backwashing. Generally, check weekly and add water whenever it drops below the midpoint of the skimmer.

Yes, tap water is commonly used. However, it’s recommended to test and balance the water chemistry after filling, as tap water may contain minerals or chlorine levels that affect pool quality.

Add water gradually, checking the level as you go. Avoid overfilling above the skimmer to ensure proper filtration and circulation.

Yes, adding water while the pump is running is generally safe, but it’s best to avoid sudden large additions to prevent overflow or strain on the system.

Yes. After adding water, test the pool’s pH, alkalinity, and chlorine levels, and adjust accordingly to maintain a balanced and safe swimming environment.

The ideal level is typically halfway up the skimmer opening. This ensures efficient skimming, proper pump operation, and prevents damage to the filtration system.

Adding water will slightly affect temperature, but it’s more efficient to use a pool heater or solar blanket for significant temperature adjustments.
