Go with what he's got, or change it up? (1 Viewer)

I've got an aquaintance with a tank, roughly 225 gallon acrylic tank. I'm going to be building them a sump, but in talking...and examining the tank, he has some complaints about noise from when they previously had it setup.

Tank is roughly 18" front to back, 30" tall and 96" end to end.
They have an HotB overflow, maybe 5"x3"... oddly enough, it looks like at one time, it had 4 holes drilled every 16" or so, along the center line of the tank... that have been 'capped' by 'gluing' 1/2" squares over the holes.

Wondering if they might be better served by building/drilling to use an internal overflow that comes out the back...rather than the smallish HotB on they have, or perhaps finding a aqua-scape design that could allow utilization of the holes that were previously capped.

It would seem to me that you would have more options to make a drilled overflow quiet ... Not too much you can do with a HOB IMO.

I would set up a BeanAnimal drain system on that with the intakes inside the tank and the drain pipes outside the tank. When they are tuned, they are virtually silent. The only drawback is the tank needs to sit 2-3" from the wall for plumbing clearance. See the one RocketSurgeon built on here, or the BeanAnimal thread on Reef Central.

Heck they're (owner) is talking 6" clearance, which is part of why I brought up the internals instead. I personally think his overflow is too small for the size/dimensions of his tank.

I agree. Seems he's got to have issues with surface skimming.
