The corraline will be bright green, then turn to purple.
I bought some Premium Fiji pre-cured lr
over the net. I had it shipped overnight to prevent excessive die-back. When it arrived, it was 100% mottled beige/brown and looked as dead as dead gets. There was absolutely nothing on this rock. I was VERY disappointed. After 5-6 weeks I noticed quite a bit of bright white coverage that looks like white enamel paint. Within another week or so I noticed tiny pinkish dots developing in/on the smooth white surface. I'm assuming that the white stuff is turning into coraline algae but I won't be sure for awhile yet. I hope so because so far nothing else has developed on this rock.
For whatever reason my calcium readings are in the 200's, despite the fact that I do weekly PWC
's with IO salt. I've been dosing with C-BALANCE for more than a week and the levels have been rising slowly.
By the way - On my new IO Calcium test kit I had a reading of 270-285 after dosing for a few days. I brought a sample to the lfs
. They got a reading of 350 on their Salifert kit. Go figure ???????
