I dont understand why but I'm on my third and final PC Rainbow. Out of all the acros and milli's I have, smooth skin, deep water, designer it's the PC Rainbow that will die on me if I look at it wrong and is he slowest grower. This one has been in my tank for 3 months now and haven't even encrusted the frag plus more than 3-5mm. I had a slight increase in po4 from .12-.2 within 2 days (forgot to turn cheato and GFO reactors on after maintenance) and the coral bleached a bit on base while every other coral in the tank was fine.
Any tips for this pita coral?
