I'm not forgetting and I know the OP was just talking about general SW
, but I like to give out advice catered towards the more reef side because most people end up going that way before too long. I would rather tell people about the slightly more complicated issues with reef to prepare them.
I'm sure SeaWorld runs all mechanical filtration as well, but for a LFS
and larger setups, its a little easier. They can justify spending big money on a 4' skimmer and other things because it is their livelihood at stake. For the home hobbyist, especially one just starting off, I believe having LR
is a safer and more effective system. I think there is less risk with a natural filtration that will keep on filtering no matter what, as compared to your canister crapping out one weekend and you are out of town. Not trying to be argumentative, just sharing my personal philosophy, which is why I tag these as, just in my opinion.
