Do other people have the same issues that I do with the rubber suckers that attach filters to tank walls? Mine fall into two categories, either they attach so strongly that getting the filter out for maintenance is a trial of strength or, as they get older, they lose the will to hang on so that the filter just falls off. I've recently replaced one filter which kept falling off and now another has the same problem, it has four suckers but they have lost their flexibility and all grip. Unlike heaters, each manufacturer has their own sucker design and attachment to the filter so that they seem impossible to replace. More expensive makes seem no different from cheaper ones in this respect. I tend to call rubber suckers by a "sounds like" name .............
Maybe some people have found alternative attachment methods?
