How often do you turn off your protein skimmers??? Do you let it go 24/7 or for a certain amount of hours a day??? What is about the right range to skim???
I do agree about leaving them on 24/7. But I have a huge bio-load and some are in fact filter feeders. If I let the skimmer run wide open all day everyday then something is going to starve. So for my system, I need to back it down.
