My experience is it’s extremely slow growing. I got one about 6 months ago, took about 3 months for the pinks to come out, now it’s one of the brightest things in my sps growout(horder) tank next to the JF jolt. I dose captive8 traces everyday, my no3 is about 15(have to dose everyday), po4 is about .65-.75. Colors after 6 months look amazing now, I’ll post a pic a little later when I get in.
