I just bought a 55 gallon tank ..used..and it already has the filters with it ..they are aqua tech 20-40 filters and i have 2 of them. my problem is that the extension tubes are not long enough..does anyone know where i could get some of these?
Sounds like you are talking about an under gravel filter. The tubes for the aqua tech 20-40 filters are meant to be below the water line, but in the gravel. You need a gravel cleaner to clean the gravel.
no im not talking about an underground filter..im talking about the ones that hang on the back of the tank and have the tubes and strainer in the water..i always thought they were susposed to be an inch from the gravel..is that not right?
