Why is my hot tub water cloudy even after adding sanitizer?

Adding sanitizer will not solve every cause of cloudy water. A dirty filter, suspended particles, a build-up of oils or water that has been used too long can leave a haze. Water balance also matters, so check pH and alkalinity as well as the sanitizer reading. Use the circulation and retesting times on your product label before deciding whether another adjustment is needed.

Clean the filter as its manufacturer directs and check that the normal filtration cycle is running. Avoid adding several treatment products at once to chase a clearer appearance. If the haze remains, take a fresh sample and your treatment record to Legacy Spas for a showroom water test. Wait until the problem is resolved and the water meets the required chemistry levels before using the tub; clear-looking water alone does not confirm it is properly sanitized.
