So just my 2cents being someone who was in a similar situation a few years back.
I don't know your financial situation but I think money is the biggest factor. I tried to do it cheaply when I first got into this hobby and it just was so hard. Yes its of course possible, but starting out with good equipment that will last is soooo much easier than trying to make basic lights and barebones systems operate. I tried so hard to make a
fluval flex 15gal work with basic equipment and it just failed spectacularly. I have since upgraded with proper lights, pumps, and larger tank and have seen explosive growth in corals. This could easily just be me and could have been mitigated with proper more effective research. However, it's not always that easy. What works for one experienced reefer who is setting up a low budget tank may not work for the inexperienced reefer. I feel like its a lot more nuanced than freshwater.
If you set yourself up right from the start it'll be a lot easier is what I'm trying to get at. So if you can drop a bunch of cash off the bat go for it.
The other thing is water storage. For me this is problem because I live in a 1 bedroom apartment. I store my mixed salt water and rodi water in 2 trash cans in my kitchen but it does take up significant space. Having to have enough mixed saltwater on hand to do significant water changes in case of emergency is paramount imo.
Automation is another thing. It helps so much. Trying to set up a basic light to run on a timer works but having one of these more advanced lights that I can program lighting schedules and spectrums from is so helpful. Same goes for pumps. Customizing my flow patterns throughout the day allows me to blow all my gunk up at certain times while giving my fish time to swim a bit easier throughout the night.
Auto top offs 100% required.
Lastly,
get a good and properly sized RODI system. I personally love my BRS system it gives me more than enough rodi water with all the bells and whistles to make me happy. I tried for about a year to use a basic robuddy and just...nah....after i upgraded I will always suggest the bigger investment.
I guess its just if you're willing to take the time to plan all these things out to make it easy to be successful. If you just jump into it...like i did...its not particularly fun and made me dislike saltwater just due to my own shortcomings.
