This morning I turned back my skimmer after forgetting to turn if on after water change last night. I noticed the water level inside the skimmer body is 1 or 2 inches lower than before. I could not raise the water level any more. It was like the pump cannot push more water. I also changed the sock this morning as the water was cloudy...Not sure if there was another issue besides the skimmer. There were a lot of micro bubbles pumped to the DT. I remember reading somewhere that new socks causes micro bubbles.....Don't think I have this issue in the past btw. Pump is about 1.5 year worth of use.
