Hi there. Personally i couldn't live without my skimmer i don't think. When I clean it out every other day it is full of really nasty gunk so I'm glad that's not in my tank. lol
I think if you really keep on the tank and pwcs, like stated above you could probably do without.
I also have the remora and its worked out great for me, have you tried cleaning it out completely? Or maybe the pump is bad? Just a thought, hate to see it go to waste considering how much they cost.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
