Keep the water clear without spending the day on it
Published 2026-11-10 · Xavier Hure
A fountain stays pleasant when the water is clear and the pump is free.
The useful rhythm is the one on the refill: 30 days for the PIXI, 2 weeks for the Dockstream, 2 to 4 weeks for the Basics.
Light care
Rinse the tank with clear water and change the filter on the pack’s interval.
Several cats
The more cats, the faster the filter fills: keep a refill nearby.
