Boom's 60G total Reef

[Boomboy]

i think i want to get around 600gph (being the low end) to 800gph. im leaning more towards the 800gph, and the rest of the flow is powerheads 2x koralia 4, i also have a Kora 2 that i might use to for any dead spots. also does anyone know if this is a good skimmer or not? http://www.bulkreefsupply.com/Protei...duct_info.html
It's rated for 125G but with my sump it will only come to a 90G system, and im guessing that heavy stocked it can handle from 60G to 80G somewhere in between. any help would be great thanks again.
The build has come to a slow creep now. Ive been to walmart to get krylon fusion white and they never have it, always all the other colours. My back and my tubing except the lighting supports will be white, even plan on painting my locline white to blend in. ( they are black to help with algea, but im ok with that for the over all look). so waiting on that to paint the back and planning out my plumbing as of now.
