External Filter or cannister filters, the best type of water filtration for fish tanks that you can get. They are more able to mechanically filter water than most sumps because they are pressurised. So are better at keeping the water crystal clear as the water is forced through the media. Cannister filters are much easier to maintain than a sump as you can take it somewhere more convenient to clean. There is no damage to the aquarium cabinet as with the humidity from open type sump filters. Chemical media such as carbon works well inside them because of the way the water is forced through the media. Sparkling, crystal clear water guaranteed.
External aquarium filters are virtually silent.
External aquarium filter are silent in operation, no weir noise no balance tap to adjust no durso noise.
