This is the first LPS I have ever bought, I don't know at that time so it is already bleached when I bought it.I wouldn't say my water is good but other LPS in my tanks grows OK. NH is 0.1 while others are 0, I have kept this GBT for almost a year and it still looks not very well (although the tip of some tentacles are still brownish), can I still save this poor guy?
