I've been looking for a new tank, and 90 gal would be ideal. However, I've found most 90 gals are set up for a sump filter. One person said for a tank that large, you sort of need a sump filter, but she was talking about her saltwater fish... Do you need a sump? Or would a fluval 404 suffice? Also, has anyone used a sump tank but not a sump filter?
I'm completely clueless when it comes to sumps, so anything posted would be appreciated
