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 ad-
equate 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 hours, 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 litres
50108 (CPF-350B) = approx. 170 litres
50114 (CPF-350C) = approx. 250 litres
After a period of 2–3 weeks, nitrifying filter bacteria will collect inside the filter sponges. These will re-
quire some time to have an affect on the water.
The pursued time period that the used pond pump needs to fill the filter once entirely, is about
1.5–
3 minutes
with the filter volumes named above. A well running filter thus does
not
require cycles of 2–
3 times per hour. Depending on the size of the pond, cycles of 1–2 per 10 hours are sufficient.
Calculation sample:
A pump filters
10,000 litres per hour.
This means that an example pond with
100,000 litres volume
needs to be filtered once entirely per 10 hours. Thus in 24 hours, the pond water needs to be filtered
2.4 times by running through the pond filter.
As the filter holds
250 litres
of water and
10,000 litres
can be pumped through the filter per hour, this
means that the filter is filled approximately
40 times per hour
with water. Therefore the filter is filled
entirely with water
every
1.5 minutes.
This means the water is processed by the bacteria for 1.5 minutes, allowing for the water to be cleared
and be released as clean water.
Intended Use
Products of this series are ideally suitable for the cleaning/ purification of garden and fish ponds. If
properly used the pond water will be effectively cleaned.
Environmentally biodegradable filter materials clean the water by means of mechanical filtration of
bacteria and waste.
Features
(partially optional)
Water is cleaned more efficiently using a UV lamp before filtering it.
The bio filter works especially strong due to its big filters and the multi-chamber system and
has an easy installing and cleaning thanks to its modular structure.
The special water flow design that guides the water into the filtering chambers reduces the
pressure on the filter sponges and additionally lowers the maintenance requirements.
The optimal design of the filter device enables an easy cleaning.
