Wow, that is an insane amount of growth. Can't wait until my lights come in so I am no longer woefully underpowered. The growth rates in my tank are measured in geological time frames. I wish I was kidding.
Also same thing with my rosé millepora. It's tips have turned a baby blue color. Both frags have been growing well, have beautiful bright color, and the Milli has amazing PE. The rd polyps are rarely out.
I noticed that when I put it in higher lighting. Mine is in about 400 - 500 par and has acquired Bluish tips. In the past the tips were more of a white color. Coral is happy growing and looks great so from my perspective it looks normal. For my RD the polyps only come out at night and they are translucent. Look closely tonight. Throw so oysterfeast in there you will see them for sure.
That makes sense, they were white and I gradually turned my whites up 2% over the last 3 weeks and that's when they color change started. Ill try out the ouster feat tonight. How long after lights out?
