Been fortunate-going from 55g to 12 years in a 120g and then last 2 in my 180g. Fortunate to stumble upon an awesome lfs with an owner who’s information and guidance was free as he would always say. Never steered me wrong, wasn’t in it for the $$, was truly about educating reefers. Fortunate that besides 1 mass extinction that wiped out all my fish early on, i’ve had minimal issues.
