I bought my reef octopus BH1000 HOB skimmer about a month ago and it worked fine for two weeks. Now the fill box fills up with water very quickly to the point where its full 20 minutes after I empty it. Last night the whole skimmer had water to the edge of the box and started to pour over after I tried taking water out. I unplugged it and let it empty and then re plugged it in and it filled to the top again and tried to overflow. HELP?
