Prior to this tank .At the end of the day, corals need proper parameters, proper nutrition, proper light (if photosynthetic, proper flow, and lack of predators to thrive. Once you understand this, you can see how simple/complicated you can make it. The basics will be the same.
I’ve never had any issues with corals .
My last tank was mostly sps and thrived for years before cracking and leaked
The transfer was what caused the crash ..
