My purple is spreading like *mad* (rock went into the tank from LR
.com on 11/17). I have several base rocks that are already well speckled with purple growth and my overflow baffles are starting to speckle as well. When I move the rock around I rub it on my base rock a bit, after having read here that scraping the coraline helps it to spread. I also keep watch on my calcium and keep it up around 420, of course, making sure to keep my alk
in line as well. There were a couple of spots on my live rock that had faded to white and they are purpling back up now too. I do have some green coraline growing strangely enough on one of my base rocks in spite of the fact that I didn't really get any/much of that with my order of LR
. I'm also running 4x65 10k and actinics. I generally light my tank from 2pm to midnight. (2-8 10k/5-12 act).
I started with IO salt and have since switched to Reef Crystals which is what my LFS
water is salted with. I'm much happier with the RC salt. The Calcium, PH
are a lot better "out of the barrell" with it.
