What are your exact readings for SG, ammonia, nitrite, nitrate, pH, and phosphate? Any other readings you take may also help.
How long has your system been set up?
How much live rock and live sand do you actually have in the tank?
As of the moment, your problem doesn't look that bad, but it's not possible to tell if this is part of a normal tank getting started up, or your about to have a big giant algae farm.
For a 37 gal tank, it doesn't look like you have enough live rock in it. Typically you want about 1 to 1 1/2 pounds of LR per gallon, so you tank should have about 37 to about 58 pounds of live rock.
