A little help please. Put a plate coral in my established tank, all levels good and temp 78. In 2 days 100% bleached out. Put another one in last Monday, same vendor and starting to bleach out quickly. No other corals close by?? Help, going quick. Thank you!
Are you sure that’s a plate coral? Dies it have a center mouth? Can we have a top down pic?
It looks like montipora or a plate formation sps, and requires certain parameters - alkalinity (crucial), calcium, nitrates, phosphates, etc. lighting is important also. Any incorrect item will cause bleaching and rtn / which is overnight death. Acclimation is important also.
