My AQ50's fit without fuss which means they should fit up to a size 50. Others require you to enlarge the white rubber grommet that holds them. One of mine had a small burr where two stitch seams joined. I knocked it down in about 30 seconds with a small file, but keep an eye on it when you get it. He would have easily killed the fish. I'm curious to see how much dirt gets in, but at least with the Aquaclear it's really easy to remove the U-tube/extension. I'm giving 3 stars because I didn't have to make my new product myself, although it really didn't matter, it could have been for someone else.
