For alternate cleaning. If sponge is the only media available for your internal filter it is tasked with performing the roles of both mechanical and biological filtering. The sponge needs frequent cleaning, yet cleaning risks the bacteria colony.

Thanks for the replies, i am wanting to get used to using setting B since switching to it though, i have a feeling like thinking the filter isnt even on and if it broke i may not even realise its broke until the fish were dead, basically because i cannot see any movement at all from the filter now lol Hi I have a fluval u2 filter, i have always used the top outlet with the venturi system, my tank is more planed than it was originally, theres currently about 4 or 5 plants in it, the tank is 64L. as mentioned above though, should i be fully submerging the filter now and take the top outlet and venturi off?
