I have a 45 gallon reef tank with 60 lbs of live rock. I am currently running a bak pak II protein skimmer. Recently, I have been gettin a tan powder like substance collecting on my rock and corals. For the last month or so I have been having a hard time keeping Nitrates and Nitrites under control. I only have a yellow tang and 2 green chromis in the tank, along with a cleaner and 2 peppermint shrimp. Also, I have noticed there is not much going into the collecting cup. Can anyone tell me why the skimmer isn't working? How do I fix the problem without buying a new skimmer?
