First reef tank build - marineland 150xh 48x24x30 - need help!

Well first of all I am already $450 in the hole with this giant paperweight of a tank (155 bowfront tank) with so many **** problems with it. Front brace was cracked, top/bottom left was chipped etc. So I decided to trashed the entire thing.
I ended up buying a 150XH brand new, never filled, back is painted black. It also came with a custom built, extremely sturdy stand!

My equipment setup:

• ASM G4+ skimmer with a 900gph Serra model: KSP-9000 pump
• Aquac EV180 skimmer with a mag 7 with an external crap reservoir
• Return pump: Quiet One Aquarium Pump 6000 - 1506 gph
• TEMP lighting - I plan on buying 2x Photon24 with 60 optics.http://img.tapatalk.com/d/13/03/11/de6y3ary.jpg - What brand is this light?
• For sump I will be using the All Glass Aquarium Megaflow Model 4 Sump
• 4 Stage RO/DI Unit (This is DI too correct?) http://img.tapatalk.com/d/13/03/11/u8y9e5u4.jpg

Questions:

• Which Skimmer should I use? I believe the ASM G4+ is the much stronger one? Pic comparison:http://img.tapatalk.com/d/13/03/11/8a3yda9e.jpg
• Is my sump big enough for a 150 gallon?
• Is my return pump strong enough?
• Any other recommendations?
• What else do I need?

 

So far, sounds good!

Sorry about the bow front, I personally never liked them anyways, ;-)

 

The megaflow 4 is good for 120-200 gallon tanks so you should be good there.
You'll get different replys about the skimmer but I would run the aquac inside the sump (not sure what external crap reservoir your talking about) and at some point upgrade the mag 7 to a mag 9.5. If you can get the sump water level at the height of the drain it will make little to no noise. There should be a gate valve at that drain. Level the water so it's right where the black box turns into your clear skim mate tube with the gate valve. That's a good skimmer IMO. I have one

By crap I meant skimates lol

The ASM g4 is crazy big. I think I might turn my 75 gallon into a custom sump. How can I divide into sections? Acrylic at Home Depot?

Go with glass. They will cut it for free, It's cheap and silicone sticks to glass way better than acrylic

 

Glass is cheaper than acrylic? Home Depot will cut for free?

 

I'm pretty sure it's as cheap as each other. In any event it's tuff to get acrylic to seal to glass. Lowes cut all my glass for free. I'm 99% sure Home Depot does as well. Get some fine sand paper and clean the edges before you put your sump together. The edges will be sharp.
