loss of coraline


New member
I just upgraded my lights from 175s to 250s on my 125 gal mixed
reef. The corals seem to love it but I have noticed a fade in the coraline that covers the rocks. Is this normal, and will it grow back? The bulbs are 14K hami with no suppliments. Thanks.

Yes, normal. I am going through the same thing right now. It will grow back. Just make sure your calcium is around 420 or so.
