What I have noticed in my 1+ grows is that I have the same green slime on the inner walls and on the air tubes. This occurs at the beginning of the grow, say the first few weeks. Presuming you have the SH bubblponic res, which is blue, light tends to penetrate the cover. I clean the walls and tubes every drain and replenish (weekly). Once your plants grow a decent canopy it will cut a lot of the light from reaching the cover, and the problem just goes away. If it's real bad, then some kind of action, such as black duct taping the res lid, may be required.
Peace

Yeah i've already tapped it up with some of that reflective tape.
