Hello! Im fairly new to reefing, something I am a bit confused about is the equipment I need to have a flourishing tank. I hear people who have calcium reactors, GFO and Carbon reactors, UV Lights, ect. Im a bit overwhelmed by all of these things and was wondering if they truely are needed? I plan I having a sump with a skimmer, filteration and refugium as well as a dosing set up. Are reactors nessecary? They seem like an easy way to over complicate things in a tank. I plan on having a semi-heavily planted coral tank with the possiblity of anenomies being introduced farther down the line along with fish. Thanks!
