Filter not working at all
Hi. We have a bio filter which came with our 100 litre tank (unknown make) purchased 2 years ago from our local pet shop. Today we discovered that it's not working at all. We have checked the impeller to see if it is blocked and this is not the issue. After some research it's possible that the motor has burnt out. Does anyone have any experience of successfully repairing the motor? Also, if unable to repair, how do you you go about finding out the make of the filter itself so as to replace it. The model number is aa390 and that's all I know. (For info, the impeller pulls water through to a box at the top of the tank, which contains bio balls, carbon and white stones). Apologies if I don't sound very technical, I am a novice. Any advice would be greatly appreciated. Thanks.
