Encrusting monti bleachimg or so.ething else

[Knightreef]

So everything else seems to be fine and this monti has been growing great. All of a sudden it is turning white from center out. Thoughts?

What are your levels

I've been battling high phosphates for a few weeks. I suppose that could be the cause of it. I was wondering if it looked like it could have something was eating it.

Looks like the polyps bailed. I guess it could be the phosphates if something changed.

How high? My monti bleached out during a high nutrient period. I thought it was dead but it recovered

 

[Knightreef]

phosphates between .1 and .2 for a few weeks Finally have them consistent at .06 now, Nitrates 10-20. Alk dropped to 7 but it is now back between 8-9

Alk drop is a maybe
What else would cause this?

Alk spike
Low or high ph
Too little flow
inadequate lighting
Salinity high
Mag high
Monti eating nudibranch and they’re small
Calcium deficiency

light burn is my suspect. Second is nitrates

Thanks, I need to double check my calcium. Need to pick up a new test kit for that

I'm leaning towards an alk spike. Has the whitening progressed at all since initial posting?

It does not appear to be spreading. If it is it is going very slow. Some have told me i should remove it and dip it in case of nudis just to be on the safe side.

So, I was able to check my calcium today and it was at 380 (salifert). It's usually in the 450 range. Do you think that would have anything to do with it? I may still pop it off the rock and dip it anyway.

Low calcium can upset the coral - yes
