I believe I found the fixture I want to go with. It will give me 440watts of VHO
lighting. It is 2x 50/50 bulbs and 2x super actinic bulbs at 110watt each. The only bad part is there is only 1-switch so I can't create dusk/dawn. My plan is to use my current NO 40watt fixture to create this effect. This gives me 480watts at 6.4 watts per gallon for my 75gallon tank, which is only about 18" deep. Is this too much light for my fish, or do you think I will be ok? I have a hippo tang, 2-clowns, 5-green chromis, 2-cleaner shrimp. If I have to, I can go with a 3-lamp VHO
giving me almost 5-watts per gallon, if that is better for my fish??? Thank You.
