lights on my 90

[drew_tt]

I think I will be going with 2 X 250W 10K with HQI ballasts...
the thing is my 90 gallon is 48" x 18"... I currently have a twinstrip of NO & PC, each of which is 5" wide...
I also have two large hang-on aquaclears which take up about 2" each at the back of the tank...
I want to keep the pc's & no's, but how would I go about setting up the mh? I will not be able to hang them above the tank by any means, and I will not be building a canopy (although I would like one I have no time for it and could never do it!!!)
so this is my setup pretty much so far:

w=water as viewed form above... sorry its probably hard to read...
would I be better getting rid of the NO's & just putting in MH's?
what would be the best way? also I am afraid of the mh's heating up the pc system and possible melting/warping/ruining it... with fans on, would it be possible?thanks, I hope to get my lights on soon!

I would suggest sellin gthe NO's on ---- and use that money to get 400's and put the 400s smack between the PC's
Mine will look like this
========================= 48" 40 watt N0 18k
========================= 48" 40 watt N0 20k
400MH 400MH
=========================48" 40 watt N0 18k
=========================48" 40 watt N0 20k
I also have a 4 foot 90 gallon tank
I am still up in the air about wheather to get 6,500, 10k, or 15k, MH's
