Im switching over to a sump. I have the 92 corner...will a 15 gal sump be alright for that...thats about all i can fit comfortably under my tanks. It has the drain portion that overflows into the refuge then flows into the return area where the skimmer and the return pump are housed. Im hoping this will be good enuff in size cuz im runnin low on room. Let me know...thanks
