Pick a single source with a proven example you like (seriousreefs for instance). It’s not to say that way is the only way or the right way, but it will give you something direct and tangible to follow with results that are shown to you. Too many cooks can very quickly enter the kitchen in reefing

Thanks I guess I’ll just follow one specific guide and hopefully I’ll get the hang of it

Welcome!

Dont jump in until you have read a ton about it or watch the BRS youtube video.

As far as size goes, here is my advice. Yes, this hobby is addictive, much more than freshwater. Get the largest tank you can fit/afford. Stay away from anything under 40-50 gallons (40 breeder is my recommended minimum). Eshopps, Innovative Marine, and waterbox make good reef ready systems that include plumbing and sumps. You get what you pay for. This may sound like a lot but I would start with a minimum of a 75-130g tank setup. You're going to end up wanting those awesome fish and room for coral colonies. That size is just the beginning of what will get you there. If you want tangs down the road, you're going to need to be able to house them.

You also need good test kits. I recommend for Hanna for nitrate and phosphate and salifert for everything else. Do you have an RODI? You will need one of those. You will need a refractometer. You will need an ATO. Read about all the eqipment.

My one piece of advice: Never, ever, EVER let you nitrate and phosphate sit at zero for an extended period of time. You may get dinos, which could be a disaster for you tank. I have known multiple people who decided to start their tank over as a result of getting an outbreak. Also, have fun!

Welcome!

I’m way more excited than I probably should be!

You may be right! Slow down, read a lot (including, no *especially* right here on R2R). I'd say take no other action until you weigh options and opinions and start to make some of your own decisions. A rough plan should start to come together in your head. Make your system your own. Only you have to live with it. When you feel stuck or torn, ask for help.
Answer these (not here, just for yourself): What do you want out of a reef tank? Everyone will have a different answer.
How much time are you willing to spend on maintenance each week? What is your budget?
There are pros and cons to every decision you will make. Few are right or wrong. Ask five different reefers a question and you likely will get eight different answers.
