Why is it when you say you are using a scrubber it creates a huge stir? I joined into a discussion on RC and boy did it create a stir. The subject how important is a good skimmer. Of course a lot of people put its the most important piece of equipment you can buy. I brought up algae scrubbers and it seemed like that was what the original poster was looking for, he even pmed me to ask me questions. But everyone else all I can say is wow.
