I have a heavily stocked 75 gallon reef.
My Remora didn't cut it.
I just added a sump and an Red Sea C-Skim 1800.
It was a pain in the ass, but it's making nice stable FILTHY foam, well worth it. (now that I got the damn tapwater conditioner out with a LOT of carbon lol)
Check out this Bermuda Aquatics unit! My LFS has one on a show tank & it's pretty damn impressive. @ $249.99 it's in your range.
