Check ultra-fine filters for hidden clogs
Ultra-fine filters can hold tiny particles, including sand and dust, even when they look clean. Check their color after rinsing. If they no longer rinse back to white, they are clogged, and replacement is recommended.
For replacement filters or help choosing them, contact Poolbots' pool experts through live chat or by phone.
