About a month ago my protein skimmer was overlflowing so I turned it off and forgot about it. Since that time, my corals have never looked better (I have a mixed reef tank). My zoas in particular are bigger than I've ever noticed and mutliplying at a good rate. I don't know if not running the protein skimmer is the reason but is there a chance it was pulling too many nutrients out of the system? Does anyone not run a protein skimmer at all? Another option I was thinking about was putting it on a timer and just run it during the day.
