Definitely, you don't need more than 2. My fixture on my 75g only has 2-48", 54W bulbs and that is more than enough for anything. What type of bulb is in it? They sort of look like they have a blue-ish tint.

one is the plant bulb and the other is the 6500k bulb, the back of the tank is blue and there is a blue led bubbler in the back on the bottom i set it up different when i added the light, im gonna get new ones in the next few weeks, are the 6500k bulbs what i really need or is there differnts ones i need for it

It is up to you and what you like. 6500k and 10000k bulbs are the most common and the plant growth is not any different. I use all 6500k because I like how bright it makes my tank look. Didn't like the 10000k light too much.

cool thanks ben i just get 2 more 6500k bulbs, and replace them, i think the bulbs are alittle older they need replaced anyway so to spend 50 bucks for 2 new bulbs is not bad

I don't plan to replace any of my bulbs until they give out. There is way to much conflicting info out there that says replace them every year and just as much saying ignore that. My feeling is if my light is already pretty high, over time if I loose a few lumens or whatever, it's not going to hurt me.
