I have a 55 watt AH over a two foot wide bow front 26 gallon. I don't keep the glass on top to get more light in the tank. I could always use a bit more light than one AH 55 watt on that tank, but not alot more.
You should be able to add a bit more light without a problem, but like Rex said, start slow and add a bit more if you want. Less light for now will help solve the algae issue, depending on your plants.
Is your 37 gallon an extra tall 30" wide tank? Because that will affect things abit too, allowing more light. bob
