Eheim Internal Filters

For smaller aquariums, Eheim Internal filters do perfectly. These efficient Eheim internal filters hang on to the lip of your aquarium or are secured using a powerful suction pad to your aquarium glass, cleaning the water with both mechanical and biological filtration methods to achieve clear, healthy water.

Eheim internal filters have been in development for years, and are regarded by many as some of the best money can buy. Surprisingly, they are sold at extremely affordable prices by Swell UK, where we try to give you the very best for less.

The Eheim Aquaball range of filters feature a completely unique design too. Drawing the water in via the outer casing that acts as a strainer, Aquaballs feature several stages of coarse and fine filtration to remove the maximum amount of dirt and chemicals from your water, with flexible return outlet, adjusted by the ball socket design at the top, giving you greater control over your return direction.

Bought at money saving prices at Swell UK, they are easy to maintain, feature a long life span, and can be with you as early as the next working day when you buy before 3pm Monday to Friday.
