Hey Soggy there is a lot of talk on this site about 12 v.s. 24 and some even less than that. What is right? Well you can't go wrong running your air 24/7 once you run the proper start up. Is 12 hours a day at night only wrong? No I don't think so. Like George said though once you get them fish at bigger size in your pond and they start sucking up more D.O. do you want to take the chance on them going belly up over an extra 15 or 20 bucks a month on your bill? That's up to you of course! I will be running mine a min or 12 hours this year and may start going to 24/7. As old as my pond is and as muc silt I have in it I am learning more that I should be running mine 24/7. Once again as mister Bill Cody says. (It all depends).
