So what I'm implying, is that an intank DSB will greatly increase the total DSB size.
check your dimensions again. By the time you got your skimmer fitted into the first chamber, and your return pump into the last, you would have used at least 1/3 of your sump.Hi guy i am new no tank yet.
I was planning on putting a DSB below but the size would be almost the same as the tank.
