Eheim Pickup 45 Replacement Filter Cartridge
Replacement filter cartridges for the Eheim Pickup 45, designed for both mechanical and biological filtration.
These cartridges remove dirt and waste through mechanical filtration. During use, the filter media surface develops a colony of beneficial bacteria that support biological filtration and break down harmful substances.
After a short maturation period, the foam cartridges provide both mechanical water purification and biological decomposition of harmful compounds.
The cartridges are reusable. To clean, rinse them gently and squeeze out excess water. Avoid using tap water for rinsing, as it may kill the beneficial bacteria.

The filter cartridge works well in my 10-gallon tank. After a week, the water clarity improved noticeably. I rinse it every two weeks and it still performs well without needing replacement. The bacteria seem to stay active even after cleaning.

I used this cartridge for the first time last month. It took about 5 days for the water to become clearer. I noticed less fish waste and better water stability. I avoid tap water when cleaning and now it’s a regular part of my maintenance routine.

Great value for the performance. The mechanical filtration is effective and the biological part helps maintain stable water chemistry. I’ve reused it three times so far without any loss in efficiency.
