Bumping up the CO2 level without knowing what CO2 levels you have is like driving with a blindfold on.

A simple KH and pH test will give you an idea of your CO2 levels.

Also CO2 alone is not the cure for algae. You only have 5 ppm of nitrates. That's within the error margin for a lot of test kits. And have you actually tested your nitrate test kit?

Are you dosing any ferts?
Water change schedule?
