Welcome to R2R, glad your looking into everything instead of just jumping (that’s what I’m doing also). I am also toying with the canister thought. @vetteguy53081 is right about the extra maintenance and from what I have been reading if you don’t dedicate to it bad things will happen but then again the same holds true for all systems to different degrees. Good luck with your build, you may want to also check out other BRS and Tidal Garden videos on YouTube. LiveAquaria does a good job of describing husbandry and compatibility for livestock including corals.
