Fluval Surface Skimmer SK400 for Tanks Up to 400L
The Fluval SK400 Surface Skimmer removes unwanted water surface film to help improve oxygenation and light penetration for a cleaner and healthier aquarium. Over time, surface films can develop from oils on your skin, household dust, cooking smoke, fat content within fish food and more. These films are not only visually unsightly, but also reduce dissolved oxygen levels which are required by fish to breathe and decrease light levels required by live plants to grow.
- Powered operation – Consistently removes surface film and prevents build-up
- Flow control slider adjusts overall flow strength
- Intake regulator dial permits skimming intensity to be adjusted
- Output diffuser allows for uniform water flow distribution

David Metcalfe –
The SK400 has made a noticeable difference in my 300L tank. The surface film is gone, and my plants are growing better. The flow control is handy and the skimmer works quietly. No issues so far.
Grace Johnston –
I’ve had this for two months and it’s been very effective at keeping the surface clean. The adjustable settings let me fine-tune it to my tank’s needs. A bit bulky but worth it.
Alison White –
Great for a planted tank. The surface stays clear and oxygen levels seem better. Easy to set up and the intake dial works smoothly.
Jason Sutherland –
It works, but I found the output diffuser needs a bit of adjustment to match my tank’s flow. Still, it helps with surface film and keeps the tank looking clean.
