In 2 weeks time I will be upgrading to a 4ft tank. At the moment I am currently running a new INTERPET EPF 250 EXTERNAL FILTER in the old tank (9 months mature) until the new tank arrives. The new external filter has been running in my mature tank for 4 weeks now to seed it before the new tanks arrival.
As I have no knowledge of modern filters (my current tank and all previous ones years ago have had an undergravel filter) would you please let me know how often I need to clean the sponges (obviously in tank water as I know about needing the bacteria), and how often I shoudl clean these ceramic disc thingies that are also in it which apparently hold bacteria too?
