So I had a couple of montiporas and about three months ago they bleached out really bad. About two weeks ago I noticed several polyps on the tips and new growth towards the rear of it. The new growth was bright red like the original montipora. About two days ago I noticed that it started to bleach out again. Can't figure out what is causing this. All other corals seem to be doing great.. I'll post my tank parameters..
Alkalinity- 10.08 dkh
or 180 ppm
If any one has any ideas or suggestions to help me out I'd greatly appreciate it!
