Ever since I gotten my new light, I have had algae growth.

Help!!!!

Kinda slimy green algae

Can you describe it or post some pics? There are far too many different alga types that can spring up from a change in lighting, though it usually is not the lighting that is the cause, jsut helped fuel it. It could be excess nitrates, phosphates, a number of different things.
What type of set-up do you have? What kind of livestock? Lighting? Where does the water come from that you do water changes with? What kind of fish and how often do you feed?
To really get any help you need to go into detail about your system.

What parameters are zero? Need to know what your ammonia, nitrite, nitrate and phophate leves are.

$10 says high nitrate from such a large bioload in a 46, and possible phosphate from the tap..... Increase the flow to the affected area, I bet the algae your talking about is cyano. But first give it some time to go away naturally, it is extremely common for an algae outbreak when the bulbs are changed.
