Pool cartridge filter / sand filter system?

Hello everyone,

unfortunately I couldn't find a thread. There must be one or the other here who has a pool, Quick Up, frame, steel wall or even a proper one. What kind of filter do you use? At the moment we are still using a simple cartridge filter. However, I am considering switching to a sand filter. Can you recommend something? What are your experiences? We only have a relatively small frame pool 305x76cm.

It does not only depend on the pool size but also on the pump which filter you need. Your current pump is probably not sufficient for a "real filter." Do you have a wastewater connection to be able to perform backwashing?

The pump that came with the pool doesn't have one.

The pump needs the appropriate pressure and volume for the respective filter. That is why I thought you surely have to replace them as well. The filter is (depending on contamination) backflushed. This usually happens directly into the sewer or you have a large infiltration area. 1-2m3 disappear right away...
