When we bought our used 120g tank, it came with a Magnum 350 cannister, but we couldn't get it to work - it runs, but the output is only a trickle. We replaced it with a filstar XP3, but it'd be nice to be able to use the Magnum either as a second filter, or on a quarantine/hospital or even fry tank in the future.

My question is, is it fixable? I have no idea what might be wrong with it - we've read and re-read the online manual - to no avail. What would make this happen?

Thanks.
