Eheim Micro Surface Skimmer Skim350
EHEIM Skim350 – the micro-surface skimmer designed for smaller aquariums up to 350 liters. Simple, quick, and flexible to use.
In almost any aquarium, a film of microorganisms, dust, oils, and food fats builds up over time – known as the mould film.
With the EHEIM Skim350 surface skimmer, you can efficiently remove this film, resulting in a clear glass surface and improved oxygenation.
The Skim350 is designed for continuous use but can also be used briefly. When alternating use between multiple aquariums, ensure that algae spores or diseases are not transferred.

I’ve used the Skim350 in my 250-liter tank for three months now. The surface stays clear and the water looks much cleaner. It’s easy to operate and the sponge only needs cleaning every two weeks. No issues with algae buildup so far.

Works well for my small aquarium. I noticed a significant improvement in water clarity after a few weeks. The design is compact and fits nicely in my tank setup. Just make sure to clean the sponge regularly.

Great product for maintaining a clean surface. The oxygenation is noticeable, especially during the day. I use it daily and haven’t had any problems with algae spreading between tanks.
