Pump and
filter systems have to run 24 hours a day to be effective. Turning
a pump and filter on in the day and off at night is almost worse
than not having one at all.
During The Winter
In
the winter when fish are not feeding and there is less sunshine you
can clean out your pond and prepare it for the
spring. You should clean your pump thoroughly and check
for any build up of limescale. When you clean your filter
box make sure that there is no water in the UVC (Ultra
Violet Clarifier) as this can freeze and damage the
unit.
In
the winter move your pump up onto a marginal shelf instead of
leaving it in the bottom of the pond. This will help to ensure that
a layer of water at the bottom of the pond stays relatively
undisturbed and warmer than the rest, essential if you keep
fish.
