If you run a planted aquarium, you'll already know the importance of keeping a clean surface to your aquarium. In fact, with a lot of open-top tanks, it's surprising how fast scum can build up, not including any dust etc from all the electrical equipment in modern households. This dusty layer has a negative effect on plant growth and needs addressing.
The Superfish Surface Skimmer is a smart creation which sits neatly on the inside of your aquarium and draws in surface water and passes it through a sponge filter. This, in turn, makes the surface sparkling clean, allows better light penetration and gives your tank a cleaner finish.
It also helps to create a little extra water movement which improves plant growth. So, in summary, the Superfish Surface Skimmer is a superb device for keeping the surface of your water sparkling clean which improves light penetration alongside adding extra water circulation.
