Looking to start a salt water aquarium

It’s way less scary than it sounds! If your freshwater tank is glass (not metal rimmed) and never saw meds like copper, you’re good to convert—just clean it well. The biggest change is all the salty stuff: you’ll need a good salt mix, a hydrometer (your new favorite science gadget), and live rock or sand. Water changes become your new cardio. The hardest part? Not impulse buying every flashy fish you see. Go slow, research your critters, and remember: in saltwater, patience is a virtue (and cheaper than fixing rookie disasters).
