Ok so I'm running a coralife 220 skimmer. I know they are not the best but right now it's all that is in the budget. I don't have room in the sump so it hangs on the side. The other night I woke up luckily and heard my return pump gurgling air. I look at the sump and it's so low the pump is dry. I see that the skimmer decided to overflow all of a sudden. I have the small tube running down to a large container to collect the run over. Does anyone have any ideas of how to prevent this If I wouldn't have been home it could have been a real mess. Thanks for all the help
