Purple Nana Color Change

[Aquattro]

Tony, you are correct. Color temp does play a role...sometimes. All things play some role sometimes on some corals, so no rules are applicable. Makes it that much more fun!!

As for the radiums, I would certainly not try to talk you out of it....I love the color. I also have not experienced a lack of growth using them and would not consider (at this point) going to anything else.
