I have a 55 gallon,with a wet dry on the back of the tank.My tank What is the cause of this Green film on the top?Is it that my skimmer isn't doing a good enough job?My water quality is good,everything is in the safe levels.I know it probably sounds silly,but it looks terrible,and the local pet shop keeps having me buy more stuff,but it doesn't help.Any help would be great!
