What do I need for a 36 Gallon Bowfront? Opinions please...

[jctse]

I just got a 36 Gallon Bowfront, ordered 2 Koralias, and have a bunch of live rock curing in a tub. I've been running my first SW tank -a 20 Gallon Long Sumpless Mixed Reef for about 6 months (15% water changes) with some success.
I don't have any plans for filtration on this new 36 Gallon but want something. Going to do mixed reef that's heavy on the coral and light on the fish (Black clown, chromis, CUC, and a shrimp). I want to run a protein skimmer this time. Is it wiser to run something inside the main tank like the Hydor Slim Skim ($115) or since I have room in the back fit in a 10 gallon sump ( Tank $10 -Petco Sale, Overflow box $40, power head $20, in sump skimmer $?) Is there a skimmer that will work in about 6 inches of water and would that work better than the Hydor? My overhead is tight so the HOB skimmers' probably won't fit.
My other options are: Someone gave me a Phosban Reactor with some Phosban. I could easily run some GAC and Phosban. Not sure how I would trap any detrius if I took that route, maybe use foam insert on the intake of the powerhead to the reactor.

If you are able to I would go with the option of running a sump on your setup. For an idea of a diy overflow you might want to check this out https://www.reef2reef.com/forums/do-yourself-diy/88164-my-solution-non-drilled-tanks.html#post959539

I use the DIY over flow and have not had one single issue. Def better than the overflows you buy. My sump is a standard ten gal tank, divided into three chambers with 9 inch water level in skimmer and refugium sides. My skimmer is a bubble magus nac3,from brs. Just be sure to have the proper water level in return chamber to avoid overflows. This type of sump is well worth it. And my DIY overflow that I made for ten dollars works better and is more reliable than those you buy. My power goes off a few times a week thanks to my electric company and the overflow has never failed to restart.
