The Fluval FX4 is a powerful and very comfortable external filter with a very large filtering volume. The performance data of this filter are impressive: 14 litres filter volume, 3.9 litres of biological filter volume, pump output: 2650 l/h with only 30 W power consumption for aquariums up to 1000 litres content. Nevertheless the filter is very compact and fits in olmost every aquarium cabinet. The Fluval FX4 has a ingenious self priming system. Only water and power on and the filter starts to pump. There is no need for priming or sucking. The Fluval FX series features a multi-functional utility valve drain at its base, making it possible to empty the canister and perform seamless water changes by draining and refilling water directly from it (and all without disturbing your setup or tank inhabitants). As an added bonus, convenient hosing clips, located on the filter lid, allows for simple storage of the hosing when not in use.

Rigtig godt filter. der går længe, før det skal renses.Kiki M. at 04.09.2021:
Bought this for my 700l goldfish tank and cant say bad about this filter! :) It does it's job well and keeps my goldies happy. Only minus is the super tough hoses but I guess you can change them if you want... Still very good and strong, but still enough gentle filter for my fishes :)Alexander B. at 29.03.2021:
Great device, very powerful. Perfect deal. Excellent seller, Fast delivery. No problems at all!Dmitry K. at 27.01.2021:
Доставка в Израиль порядка 2 недель. Упакован хорошо, надежно. В целом очень доволен. Несмотря на крупные размеры работает тихо. Тем более если он в закрытой тумбе то почти не слышно. Раз в сутки выключается чтоб стравить воздух, сильного течения нет из за грамотной насадки на трубке выброса воды.
