How old are these bulbs? Flo's should be replaced evry 6-9mos,MH a little longer but not over one year. Try champion lighting.com 55k is a good bulb for MH but it really depends on how big the tank is,and what you have in it.

I got my system of lights on ---- they where 9 months old, I have a 55g coral reef tank.

Then I'd say that it's about time to replace those bulbs. If you let them go too long you will most likly loose any corals you have,or start getting bad algae.You don't have to replace them all at once if you can't afford to,just keep track of the dates so you know when to replace them again.
