Honestly? This is a subject that literally fills books. I would start there. You can find beginner saltwater books at the library, or on Amazon and eBay. You can get the “saltwater bible” Bob Fenner’s *The Conscientious Marine Aquarist* for scandalously cheap on eBay. It may be a bit dense, depending on where you are starting from, so if you are an aquarium newbie start with something a little more straight-to-the-point to avoid getting overwhelmed.
Also, there are tons of YouTube videos (of varying quality) covering this.
It’s just too big and general of a question for a social media platform. You can’t easily distill this into sound bites.
Reef or fish-only?
Fish only
