Mushrooms reaching to the sky

[Jus_sum_guy]

Honestly I don't know.
I bought this tank off a guy that had a gorgeous reef in it!
He custom installed where he added a 2nd switch to the hood to turn on the blue light and turn off white light and vice versa. Or have them both on at same time.

I take it I'm going to have to measure the light output somehow....?

Again....they just started doing this today after weeks of having them. Also my hammer coral, war coral and Xenia are growing FAST without feeding...
