Yep, that is right. Over the last 2 to 3 days my coralline has been turning white. It is mostly along the back of the glass. It started from the middle and worked outwards. There is some death on the rocks but no where near as much. The tank has been “cycled†for over 2 years, but was moved last August, so the Coralline completely covered the glass for a nice purple look, just not anymore.
About 3 or 4 weeks ago I had a fish die (did not catch it for a couple of days and had a ammonia spike) The ammonia nearly crashed my tank. Lost a few SPS frags, but the colonies survived, only loosing a few branches. That was followed by some algae problems so I added a fair amount of phosphate remover (Two Little Fishes Brand). As it sits right now, my across have/are currently recovering and polyps are extended. The other non-sps coral is healthy and was never as impacted about the fish death, now it is just the coralline that is being difficult. Would aggressive phosphate removal cause a coralline collapse? There has been no change in lighting or flow, as if that would matter.
The tanks parameters are:
1.026 SG
0 Nitrates
0 PO4 (undetectable)
420 Ca
1440 Mg
9.6 Alk
8.0-8.3 pH (occasionally I will see a 7.9 reading in the mornings)
78 Temp
Strange that the coralline would ‘bleach’ but I can’t find a cause that would not affect my Acros as well. The only other thing I can think of it that I spilt foot powder on the carpet near by and vacuumed it up. Maybe some dust settled into the tank, but would Lamasil do that and not kill the other corals?
Thanks
