Since I am in Texas and we have wild temp swings, the ring on my easy set changes size at least twice a day. Any time I turn the sand filter on, if I'm not standing there, the skimmer pops up and sucks air. tired of purging air. I'm also concerned about burning up filter. Right now I have a 5 lb weight tied to the outer bucket with a length of trot line. I would love to have a floating skimmer but can't afford one. Any ideas on how to engineer from bits and pieces?
