Sal 1.026
Amm 0
Nitrites 0
Nitrates 0
Phos .5 been trying to bring down
Mg1300
Ca 460
Alk 11

Everything else Is fine except a closed up leather. Need suggestions

I did a dip in revive 2 days ago thinking it was nudi

 

PH stable?

 

did you check for nudis? or a fungus? i had a clear fungus on mine and they were all closed. I kept my Ph stable and everything is back to normal.

 

You seem to be having problems with several corals lately (zoas, leather, brain) and your water parameters seem fine. I'm wondering about that foxface I see in a lot of your photos. Ever see him nipping at coral?

 

The foxface has been in there for about a year have never seen him go after anything

The brain has gone back to normal, and the leather i still have no clue, it looks like its got black spots that don't move?

Ph is 8.0 and fairly stable I don't see a fungus and did a dip thinking nudis

Should I do another dip? I used revive but could try something else

 

I wouldnt be to worried, as long as the polyps still look firm and healthy, my zoas just finish a week long closing. but are now opened and splitting, I'm in no way a pro, but I think corals just have "stubborn" phases from what I've been told

 

That's the problem there starting to shrink and shred if that makes sense

 

Water change at least when this happens to me. I dose high amounts of vitamin c

 

Should I say do research as there are side affects

 

yeah that is a problem then lol. hmmm lighting? any changes?
