I'm getting back into reefing. I have my 180g FOWLR doing great but I do miss having a coral reef so I am starting a 125 reef and just finished setting up the aquascape. So I have been reading about PAR and placement of corals which I never did in the past because we didn't have such fancy equipment or money back in the day. I was thinking about buying a PAR meter, but my question is, If I determine all the areas with the correct PAR readings does it really matter? Won't the corals grow into areas of different PAR especially corals that grow vertically? Do we just measure PAR for initial placement. Please educate me on this. Thank you.
