I guess if you're not neurotic about keeping the floor of your sump clean like I am, then they're fine :-) I try to vacuum out every inch my sump floor during every water change. Probably not necessary though. I have to remind myself that not everyone is as neurotic as I am.
Well I guess your tank always shows the fruits of your labor so you're doing something right!
