Please diagnose. Is this bleaching? If so what is the cause....seems to be happening on one branch only, the other branches show growth, rest of my corals doing well.....cal 450/dKH 8/Phos- close to 0. Any ideas?
These things happen,Bought a acro from a vendor here and it bleached in no time while my others are doing fine.Could be ph swings or temp swings,nitrates,bugs.Try clipping that piece off.Also,it can also be where they originate from.I hear that Aussie corals are more hardier.That's what I heard.
