Pond filters ensure clear water where nature itself can no longer create it. However, pond filters are not quite as easy to care for as the microorganisms in nature: they need a little maintenance and cleaning. Read our post to learn how to do it right.
The filter sponges must be washed out thoroughly
need for cleaning
Pond filters must also be cleaned during operation. This is not a difficult task in general, but above all it has to be regularly and continuously happen.
A little more effort is required when the filter goes into winter operation. At this point, you must then take some additional measures.
When purchasing the filter system, make sure that the pond filter is sufficiently dimensioned. Systems that are slightly oversized and designed for a slightly larger amount of water than the pond actually has are definitely more advantageous in terms of cleaning than systems that are undersized. These cause a high maintenance effort.
Basic cleaning
Many filter systems have a control display that shows when the filter needs to be cleaned. You should always follow this display and only clean when the device actually requires it.
Filter cleaning for filters with UVC system
UVC systems are usually the easiest to clean. There is a "cleaning mode" that you can easily activate with a lever or switch. With other devices, all you have to do is turn off the UVC lamp.
After that, you can simply push out the filter sponges and squeeze them out thoroughly. You should never rinse them out during the current season, otherwise you will seriously disturb the filter balance.
You can also use certain agents to revive the filter bacteria afterwards - the lamp must then remain switched off during the exposure time (often several days). However, this is not absolutely necessary for every cleaning.
After squeezing out the filter sponges, you can simply put the system back into operation. The pump usually continues to run undisturbed throughout the cleaning process.
winter cleaning
During the winter you usually have to remove and replace the lamp and rinse out the filter sponges. When you want to put the system back into operation in the spring, everything will be reassembled.
tips
Before installing the filter, make sure you familiarize yourself with the operating instructions and always follow them exactly. Incorrect operation can severely disturb the filter balance and thus significantly reduce the system performance.
