I just got a 110 gal and am currently working on getting the stand ready to stain. Had some water marks and I'm trimming it out. Anyway....It came with about 4" gravel (I know too much). It's a nice brown but I'm concerned it may be a bit coars for SA/CA cichlids from what I'm reading. I read good and bad on both but if it was you would you go gravel or sand if you were starting up a new aquarium? I really like that Tahitan Moon sand but man is it expensive.
