OK, with the exception of my DIY stack canister filter Iv never owned a brand name stacked canister and thought I would try a cheap used name brand one on ebay so I targeted and won a big on the Fluval 404. Only to realize too late (dummy) that it was discontinued probubly for leak and performance problems. Can anyone confirm or deny that the Fluval 404 model has a problem where, a fix, or has worked reliably for you for how long? I just want to prepare myself before it arrives to minimize any grief and a possible solution. Supposedly used once and been in storage for 2 years paid $68 with shipping, too much?
