Metal halide and PC for a 90g
I currently have a 260W orbit PC fixture on my 90g tank.
I was considering making all 4 bulbs on it 65w actinics and adding two 150w MH fixtures: http://www.hellolights.com/150wahqirelo.html I was also considering removing two of the 65w bulbs in the PC fixture and putting two retro fit MH fixtures in their place, but I'm sure how much wattage I should go for. Any thoughts or suggestions would be appreciated... I have never dealt with lighting outside of PC. Thanks!

i have seem ppl use 250watt Mh on 90g tank , about 7" above water. However, i had 65wattx4 PC for my 75 gal tank with 2" above water b4, and i just switch to 2x 150watt mh + 2x96watt pc 10" above water. it's been about 1 month now, so far everything is doing great.
If your tank are doing fine with 4x65watt pc, i'm almost 100% sure it'll be fine with 2x150watt mh + your 65watt pc. Another thing is that you probably want to keep the mh at least 5 or 6" above water, otherwise it'll get really hot.
