I broke a skimmer basket while cleaning it recently and I was looking into the validity of the skim-a-round. Then while looking at these forums I realized people were talking about weir doors (never heard of that before). No wonder my skimmers don't do anything. I have no weir doors. I can't wait to get home and figure out which ones I need. This whole time I thought I didn't have a powerful enough pump or something. I have so much to learn. 2 years of pool ownership and I just realized this. Wonder what else I'm not seeing.
