Hello folks. A while back I posted on how my Nuc Green and Purple Deaths polyps were small and staying that way. The polyps were staying small and spread out even though they were reproducing. I recently changed the bulb that was providing light to that side of the tank from a Phoenix 14K to an Ushio 20K. After about 3 weeks both PD and NG colonies are starting to get larger polyps and are filling in next to each other instead of staying spread out. They look a lot better now. I do not have a PAR meter so I can not be sure if the change is due to less intense light or maybe they prefer the bluer color spectrum. Just wanted to share as I know that others have posted about these polyp size issues.
