EHEIM Prefilter
EHEIM Prefilter
This extra prefilter traps the majority of coarse dirt particles, even before the water reaches the external filter. Its base rests securely on the bottom of the aquarium. The water is drawn in all round, over a wide surface area, through the modular filter baskets which can be filled with filter media and easily cleaned and replaced. For cleaning, you simply remove the filter baskets.

The prefilter works well in my 100-liter tank. It catches large debris like fish waste and plant matter before they reach the main filter. Easy to clean by just removing the baskets. Keeps the water looking cleaner for longer.

I installed it with my existing filter setup and noticed less clogging in the main filter. The water flow is even and the baskets are easy to remove and refill with media.

Great for beginners. It’s simple to use and has made a noticeable difference in water clarity. No issues with installation or maintenance so far.
