Should a filtration system run 24 h or can I attach a timer to turn it off at certain times?
To work efficiently the filtering system should be in continuous operation. Otherwise the pond water could get dirty again after just a few hours.
In addition if the filter is not in constant operation, the bacteria and micro-organisms in the filter mats, which are necessary for biological filtration, die off.
Consequently we recommend 24 h continuous operation for filters!
