Seems we immediately began to focus on alkalinity, and indeed 13 is abnormally high and i try for mid 9’s and some think that is too high.
But just as an aside while not by any means an seasoned SPS guy, I have been able to do well with most SPS of late. However the one birds nest that seems to be doing well in my tank right now is the first of about five for me. I understand it’s an extremely hardy Genus and stated to be good for beginners, but it is never been good for me.
Till this one anyway.
