So yesterday while I was at work and my girlfriend was home, she texted me to say the return pump was sucking air. Weird since I just filled my ATO bucket the night before. She then proceeded to tell me the carpet was soaked and water was pouring out of the sump. I had her shut down the return pump and protein skimmer. She had to leave to go to school so she threw down some towels and left. I stopped by Aquatic Art and picked up some buckets and borrowed a shop vac. I got home and figured out the problem. My filter sock was dirty and the water was pouring out through the top and over the rim of the sump. Since about 3 gallons spilled out, I ended up having to dry the area. So I emptied the DT and the sump, moved the tank and stand, cleaned the area and put it all back together. Took about 6 hours. Everything seemed a little stressed but alive. Keeping fingers crossed.
lesson learned: keep filter sock clean and below the edge of the sump.
