Gearing up a HOB overflow

[Bob]

The upside with your overflow is...if you move up or down in tank size...you always have your overflow
I have used them for more than 20 years...and still use one...on a 72 bow
Set it upthe way you would even if it was buit in....with your sump...even if power go's out they are self priming.....they work great

Thanks. I hope I have enough flow.

I've got two 1400gph Powerheads in the tank now. It's a 6 foot 125.

Two lonely little chromis and some snail/crab stragglers.
