How often should I test my pool water?

For most residential pools, pool water should be tested at least 2–3 times per week during the swimming season. Regular testing helps keep the water clean, balanced, and safe for swimmers while preventing damage to pool surfaces and equipment.

Key factors that affect testing frequency include:

• Pool usage and bather load

• Weather conditions and rainfall

• Water temperature

• Type of sanitation system (chlorine, salt, etc.)

During periods of heavy use or extreme heat, more frequent testing may be recommended. Proper water balance helps prevent issues such as algae growth, cloudy water, skin or eye irritation, and premature wear on pool components.
