Tissue regression help?

[tjsailosullivan]

Urghh!!!!! Some of my Milliporas are showing fast signs of tissue regression and have no idea what's causing it. looking for thoughts/recomendations. One of those millis have been one of my favorites. I have checked all my parameters and everything looks good. One of the millis (favorite) is to big to remove and is grown to the rock. I removed one of the smaller frags and don't see any predators.

Salinity 1.026 (Milwaukee digital refractomoter)
Phosphate 0 (Hanna checker)
ALK 9DKH, (Salifert)
Mag 1300 (Salifert)
Calcium 440 (sailifert)

Looks like you are ultra low nutrient. I would lower salinity to 24-25 and lower alk to 7dkh.
If you are carbon/bacteria dosing or using gfo I would back off a little.

How old is the tank - it looks super clean of coralline, but you could just do a good job of cleaning off of the glass.

What kind of lights do you have?

I actually started out with bio pellets but then I quit using them. Just running a skimmer and calcium reactor. I was thinking the same. Will try and feed a little more and see what happens. Unfortunately I don't know if I will be able to save them.

There's some coralline. Just like the clean background. The picture dose by really capture it well. Using a combo of MH 250W HQI xm15k and reefbrite XHO blues.
