andy120 Posted October 17, 2007 Report Share Posted October 17, 2007 Hi Ive got an aquaone 881 internel filter, the darn thing makes a heck of a racket! The powerhead of the same brand isnt to bad. Any ideas why the filter is so bad? Are external canisters quieter? Thanks Andy Quote Link to comment Share on other sites More sharing options...
