Your skimmer seems to be a bit under-rated for the system. http://www.redseafish.com/Prod126.asp the website says its good for up to 40 gallons, which means its actually good for 30. +1 to tossing the canisters and upgrading the skimmer. what size powerheads do you have? some more flow may help with the algae problems..

i would cut the light period down to 5hrs a day or even less to battle the algae problem.
maybe even a day or two of no light to start with. cloudy day never hurts the coral or fish. just hurts the algae
