Do sometimes you just want to quit?

[Leah]

I know what the feeling is to, Just when it all is good things tend to screw up I have a
major love/hate relationship with my Eheim filters. We have them on fresh and all my salt
tanks. Last time I cleaned filters what I thought would be a quick job, left one tank my
FOWLER without a filter for a couple of days. As I could not seem to get it to fill after
cleaning the hoses. Anyone out there have eheim filters that could give me a tip or two?
