So I have a Penguin 330, however it doesn't do a very good job of filtering my 38g cichlid tank. It also has an issue of overflowing around the intake pipe right at the top where it curves into the impeller assembly. The biowheels and filters are all seated properly. Yet it stilll overflows there and doesnt seem to be really "filtering" much. Can see lots of bits of old food, etc floating in water. I'm not overfeeding them as i only feed 3 times a week, and give them finger pinches of food one at a time when i do feed them so as to not overdo it.
I've been looking at a possible replacement and am wondering if it would be a better solutio to filter my tank.

Not sure what else to do, i vaccumed the gravel 3 days ago, and changed to new filters as the old ones were quite dirty and had been in for awhile. The fish are fine and ive been monitoring ph, nitrite, nitrates, etc. All is within the safe ranges according to my test kit.
The penguin 330 does ocassionaly make noise like it is having difficulty sucking up water, and ive check/cleaned the intake tube and impeller to be sure, but it still seems weak.
Let me know what you think i should do here.
Thanks!
