In my tank there's two power filters which 'ARE NOT WORKING' does any any one now what sort of filters need to be fitted into them, and how often they need to be cleaned. Cheers Ollie
thats a pretty vague request ....try googling the make and model and see what comes up or go to a marine supply site and see if they have parts and pieces for them {petsolutions.com and foster and smith are good reputable sites} or take one out of the tank and take it to your LFS and see what they can do for ya....good luck, Boss
Do you mean they are not "working" because all your fish keep dying or because the filters are actually broken and don't pump any water over/through the filter media?
you probably just need a new impellar. if you take your impeller out and feel the magnet on it, it should be one consistant size all around. after a couple years, the magnet on it will wear down and not work right.
