Should the protein skimmer stay on 24/7 or should i only run it a few hours a day? i have read mix storys on this so im confused on what i should do. some articles i have read sad to only run the protein skimmer a few hours a day, other articles say you should only turn it off when your cleaning the tank. whats your opion on this. do you keep your skimmer running 24/7 or do you let it run a few hours a day then shut it off?
