Sump? or Hang-on-tank?

[TheReefGeek]

The remora pro is a great skimmer for a hang-on model, you can't go wrong if you go that route.

BUT, AquaC does not make the best (although they are good) in-sump skimmers IMO, so if you do go with an in-sump skimmer check out some other brands.

There are ways to run a very quiet overflow setup. Mod the overflows with Durso standpipes, and use a smaller return pump to limit the noise from water going into the overflow. Airline tube in the plumbing can also help limit gurgling by allowing air to escape. Submerge the drain line in the sump a couple inches to limit noise as well, and make sure there are no really large differences in water levels between baffles, and keep the return section of the sump topped up so you dont get much noise from falling water. Benefit to a sump is that you can insulate the cabinet as well.

With the above recommendations, i think you should find that your fans for your lighting make more noise than the rest of the tank.
