Is there anything I can do about a noisy filter? I was unable to clean the pool last week and it's got some green on the bottom so I've been running the filter all day. It seems the gauge is shaking some and making a bit of noise and I hate to be a bad neighbor. I tighten the gauge again each time I clean the filter but it just goes loose again and makes for a loud buzzing sound. I hate noise pollution so I'm annoyed that I'm a source of it. Any ideas?
