Welcome to R2R! As others have said, probably the most important advice is to take your time, go slow adding things and go slow changing things, even go slow fixing (most) things. Very few good things happen quickly in a reef tank.
You have come to the right place. Lots of help on here if you have any questions with anything. we are waiting at the keyboards. I would highly suggest getting soft corals and leathers. they are more forgiving and great to get your feet wet. some amazing softy tanks out there for inspiration.
Hello everyonejust got my first salt water tank today(coralife 16 biocube) filling it up now, put a 50w aqua top heater in the back, and filled up the bottom with some Caribsea sand. I’m super excited to try something new! Any tips for me?
