Hey, well I am new I'm 16yo I am starting my first saltwatertank. I went into the fish hobby when I was 11yo. So just because I am kid to you'all lol. I am now waiting 2 weeks after the start-up and I can't freaking wait that long to get started..
What's the two weeks for? Cycling generally is about six weeks. Then adding animals one or two at a time waiting between each addition and monitoring water conditions to insure there is no increase in ammonia or nitrite.
The waiting is the worst part but its so worth it. PLUS it gives you plenty of time to do tons of research and research what you want to get (corals, fish, inverts, ect) and where you want to put everything, its so fun to imagine.
