get a scouring pad and get that glass cleaned!
have you tried spot dosing the carbon with a syringe directly on to the BBA instead of just pouring it into the tank? After reading previous comments i agree that you should consider adding Co2 injection (FE or DIY). Even with adding algae eaters and dosing the liquid carbon i would be cleaning the glass just to make it more appealing and you might enjoy it more yourself (i know algae on my tank drives me nuts).
