What causes pool water to turn yellow

Yellow pool water is caused either by mustard algae, or high metal content in your pool water. Mustard algae is gross and slimy and makes the water unsafe to swim. In either case, you should treat your pool using chemicals like shock treatment to correct the problem, before you go for a dip.

How often should you change pool water

Factors such as water chemistry balance, frequency of use, and environmental conditions all influence how often a complete water change is needed. Most experts recommend replacing pool water every 3 to 5 years, unless specific issues arise that require earlier action.
