Algae Problem

[Gizmo]

Lately I've been having a rash of algae bloom in my tank. Just the standard green, no hair or anything like that just a green slime on all the glass, noticable growth on a daily basis. Its starting to grow on the rocks and air bubbles seem to be retained against the algae, how can I get rid of this? The water quality has been great using RO/DI, No nitrates, I did have some Phosphate in the water about 2 weeks ago, but I removed it using phosban. SO. any ideas?
