Suggestion for a hang on skimmer

[intarsiabox]

I had an Aqua-C Remora on my 20g and it worked great! Lots of people have had great success with these skimmers and others have not, maybe a quality control problem? Mine skimmed about 1-2 cups of dark green sludge a week and I had no algae or cyano but I am also careful about how much food goes into the tank and do weekly water changes religiously.
