Fluval SK400 Surface Skimmer
The Fluval SK400 Surface Skimmer is designed to help remove surface film, floating debris, dust, and oily buildup from aquarium water. By continuously pulling water from the surface, this compact skimmer helps improve gas exchange, water movement, and overall aquarium clarity.
Surface film can reduce oxygen exchange and make an otherwise clean aquarium look cloudy or neglected from above. The Fluval SK400 is a useful addition for freshwater aquariums, planted tanks, community fish tanks, and saltwater setups that need cleaner surface water and better circulation.

Why Use a Surface Skimmer?
Aquarium surface film can come from fish food, oils, proteins, dust, plant matter, and low surface movement. While it is common, it can reduce oxygen exchange and make the tank surface look dirty.
A surface skimmer helps pull that buildup into the filtration flow so the surface stays cleaner. This can be especially helpful in planted aquariums, aquascapes, and tanks where strong surface agitation is not desired but surface film still needs to be controlled.

Setup & Maintenance Tips
Install the Fluval SK400 according to the manufacturer’s instructions and position it where it can effectively pull water from the surface. Make sure the intake area remains clear of floating plants, large debris, or obstructions.
Check and clean the skimmer regularly during routine aquarium maintenance. Removing trapped debris helps maintain consistent performance and keeps water moving properly through the unit.
