Everything seems to be settling in well. I started dosing at 1ml of both cal and alk per day on my doser with Mg being dosed at .5ml every 10th day, and levels are remaining stable at 7.0-7.2 dkh and 420-430 Ca. Mg is at 1360.
I accidentally dumped a bunch of zeostart in the sump and made some corals reallly angry, so hopefully they recover. The PC rainbow frag responded the worst and all of the newly encrusted growth bleached over night. hopefully it recovers :/
What size UV are you using? I've got a nagging brown algae that I thought could be phosphates but gfo isn't making much of a difference on. 2 day lights out kills it for 2 days and it comes back.
