As Anthony said, I have 3 250w de 13500k geisemans, a calcium reactor and I drip kalk.
Pictures for growth comparison, this one was taken Nov 26th
and this pic was taken Mar. 9th so it's a little over 3 months
And Anthony took a bunch of the montipora home with him a few weeks before the last pic was taken
*Edit* the reason the last picture looks so green is because the ballast for the vho's died
