Regular cleaning work

• Empty the debris tray:
– The cleaning cycle is dependent on the degree of soiling of the pond.

tributor using the brush. For this, manually activate the SceenMatic screen. (→ Manual cleaning)

Insufficient pump capacity
Insufficient circulation of the water

The water level is initially lower when new foam fil-
ters are fitted as they have not yet been colonised
by bacteria.
