I am not sure, but I just saw a minute ago a crab in my birdnest . Should I take it out? It would be very difficult to take it out. I always do coral rx dip before I out any corals in my tank.

Id Frag that and move your water changes from monthly to weekly until you see recovery.

It looks like you have algae. Is your tank in a good shape for Acropora?
Is your tank stable?

That is macro algae, not hair algae . My parameters are very stable . I am dosing daily to keep my calcium , kh and magnesium stable. The acropora was well the whole time and after my last wc it was suddenly like this. I did change new activated carbon. If I put too much new activated carbon can it harm sps?

 

[jasony816]

are you using GFO, bp? I have a similar issue and they are receding from the base very very slowly and it seems like it happens every time I do a water change (10%) every week, and gfo/carbon every other week.

its possible.

GFO more likely

 

[jasony816]

I agree with the GFO, how often should you change your GFO because I feel everytime you change it there is going to be a change in p04

hm I had a similar issue with a ORA plum crazy, started to bleach from the bottom up even though params are stable and the pink lemonade next to it is perfectly fine. I ended up losing most of it before I did like they are suggesting and tried to frag the healthy part.

 

[Kaman8]

I fragged the healthy part yesterday trying to safe it. Today when I woke up it was dead half of it. It is dying very quickly. It was so well before I change the carbon. Half of the colony was dead in 2 days after I change new carbon.
