I have recently decided I want to jump into a a SW community tank with fish and coral. Found a good deal on a 90 Corner tank that will fit perfectly in a low light corner of my dining room. I’ve watched a few YT videos and seems like everyone is building the aqua scape and then filling their tank. Am I missing something? Doesn’t the water have to cycle before adding coral or are they just using rock? I’m considering ordering “real reef” from Amazon
