I bought this on Tuesday from my LFS about 30 minutes away. I drip acclimated it for about an hour and then dipped it in Coral rx. It's not opening fully. Everything checked out in testing as Ok. Alk was a little low at 7.7 so I just dosed some today to bring it up slowly to 10 over a few days. Temp was at 80 I lowered it to 78. Here is how it looks. Under 4x65 watt pc 2x 10k white 2x Actinic. I saw a small string of what I believe was zooxanthelle yesterday. I assume this will take a week to acclimate and open but I just like to double check. I'd say flow is moderate. It sways quite a bit.
