Depending on the use of the pond, the ideal cycle depends on various factors, such as fish stock, water
plants, exposure to the sun, required water clarity, etc. Of course, further components of the filtering
cycle need to be adjusted to each other.
Basically, a distinction is made between two different ways of determining the optimal filter size and
water circulation. Both types, the optimal circulation of the pond and the retention time of the water in
the filter, are discussed below.
Optimal pond cycling
The cycling of the pond describes how often the entire amount of pond water is directed into the filter
within a specific amount of time (cycle per hour).
The guideline can be as follows:
•
Koi/fish pond:
1
cycle in 3
hours with little fish stock
2
cycles in 1
hour with high fish stock and no plants
•
Garden/plant pond:
A pond without any fish stock does
not
require any cycles. Any water/marsh plants are adequate
replacement for a filter system.
•
Swimming ponds:
The cycle strongly depends on the plants and own requirements with this type of pond. The
upper limit is once per 2–3
h, the minimum is no cycle at all.
Duration of the Water passing through the filter/filter volume
The main interest is the actual volume of the used filter with
pressureless systems:
•
50107 (CPF-350) = approx. 85
ℓ
•
50108 (CPF-350B) = approx. 170
ℓ
•
50114 (CPF-350C) = approx. 250
ℓ
