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 120-liter tank. It keeps the water clear by catching large debris before it reaches the main filter. The baskets are easy to remove and clean. I’ve used it for over six months without any issues.

I installed this prefilter after noticing a lot of dirt in my filter. It’s effective at trapping leaves and small pebbles. The water flow is even, and cleaning is simple. A bit bulky for small tanks, but worth it.

Great addition to my aquarium setup. The modular baskets make maintenance easy. I clean them every two weeks and the water clarity has improved noticeably.
