40 Gallon, Skimmer? Sump?

Hello i'm fairly new to saltwater tanks yet fairly versed in freshwater and brackish water tanks. With that in mind i have a question while setting up a 40 gallon fish only or reef tank, do i need a skimmer? if so what would be a good brand for decent power and would i actually need a SUMP for an aquarium this small? currently i will be running 2 fluval aquaclear 50-60 filters giving me 400gph filtration. As well as 2 inch live sand bed and about 50lbs of fiji liverock.

i ask only because i have limited space in the area i want to display the tank and if i can get away with no extra sump or canisters i would love to save the space.
 
It's possile to get by without one if you have a large fuge or small bio-load or do a ton of water cahgnes but I wouldn't recommend it - especially for someone new to the hobby. Ther are in-tank or hang on back (or side) skimmers that wouldn't require a sump. The ones I would recommend looking at would be the Tunze 9002 (in tank) or Aquamaxx (hang on) skimmer.
 
You can certainly keep a tank without either a skimmer or a sump, but there are many advantages to having both. Using a skimmer will improve water quality, help oxygenate the water and reduce the frequency that you need to wake water changes. A sump will add water volume to your system making it more stable and also allow you to hide most of your equipment (skimmers, heaters, filtration...). I have kept saltwater tanks in the past without either a skimmer or sump, but they do require more maitenance and don't look as nice.
 
Me personally? Yes, I would buy the AquaMaxx HOB-1 if I decided to put together a tank of that size without an over-flow but I'm sure that there are other good choices for a HOB style skimmer that would work for you. I have no personal experience with Reef Octopus skimmers.
 
Thanks for the advice i will definitely invest in a nice skimmer and possibly build a sump starting on an extra 10 gallon tank i have going to lowes today to get the glass and going to take a wack at it
 
Just to clarify. Unless you are planning on drilling your 40 gallon tank I don't see why you would want to ry and add a sump. An HOB skimmer doesn't need a sump - you just put it on your main tank and you're gtg. Now, if you are planning on building a sump and drilling an overflow in your tank then I would recommend an in sump skimmer, not an HOB skimmer.
 
I strongly recommend against HOB overflows. There's a lot of horror stories about what happens if you lose siphon. Just do a search. Drillign a tank isn't that difficult. Lots of youtube videos on that as well.
