My skimmer drains and begins to suck air whenever I have my pump on high. It runs fine on low but I am concerned because I am wanting to slam and then utilize the SWG and from time to time I will need to put it on high to go to 100%. I have changed out to a new filter because the other one needed a deep cleaning. I have cleaned it and am planning on storing it in a plastic bag and then alternate between the two, will this be a problem? Also any suggestions on the pump draining the skimmer is appreciated, thank you. Oops one more question..... I tried the skimmer sock and my husband was concerned that it might be part of the problem so he had me remove it, can anyone give me more info on the skimmer sock?
