Serious is good IF you can maintain sanity long enough to end up with a finished product before saying screw it and changing completely....
One thing I always try to shoot for with filtration is short down times.... Being able to swap out media in a few minutes.... Otherwise I put stuff off, and procrastinate to the point that it gets "bad".
I used to run canisters but after opening one up and realizing what a mess I let them get to be because I procrastinate maintainance so much (due to them being a PITA to clean,) it's nothing but DIY filtration for me from now on.....
I think you should be able to swap out all the mechanical media in a monster sump/wet-dry in the same amount of time it takes to prime a Fluval 405.
I can't be the only one that's like this when it comes to filtration......
Man, the idea of a vortex settling chamber..... That's what I'm talking about.
Sorry Mr. Carswell I respect your thread. My derail is now over......
