Just wondering what equipment is needed for this size of a tank

Welcome to the world of saltwater! Instead of the filter you have.I would suggest 1 to 1 1/2 lbs of live or base rock(I used base rock).You will need some wave makers to provide aeration. The other equipment is dependent upon what you plan on doing FOWLR
(fish only with live rock or reef) I believe the hood lighting should be sufficient for a FOWLR
but for a reef I would get a canopy or cover and do LEDs that are designed for a reef. Both the wave makers and the lights usually specify what tank size is optimal. 20 lbs of sand if you want substrate.Stay away from crushed coral its a nitrate trap.
You will need a test kit and a refractometer(its much more accurate than a hydrometer in my experience.),a small float magnet to clean the glass and a quarantine tank(although I suggest you use the 20g as a quarantine tank and go for a larger size tank because it allows for beginner error, is easy to maintain good water quality without so many water changes and you can keep more fish and/or get the fish you really want like tangs or angels for example they would definitely not be at home in 20g tank.
There are some really good articles on this site.Just go to the articles tab and you will find some good info.
