I Need NEW LIGHTS opinions????

[geopod]

I will be back home in early Nov.Now when I get back I want to get MH lights ...BUT....I have a 4' coral life 4x65w PC fixture on it.Can I somehow add some MH to that or would I have to get someone to modify it to fit with MH or Should I just buy new lights and sell off these oones?The tank is 4' long as well 90gal and 2'tall.I need some opinions from you folks.There really isnt room to leave the PC fixture in there and adding 2 MH as well.I think there would be shadows.
oh ya looking to upgrade on the skimmer as well.Anyone gonna be selling a skimmer soon?
