Green slimer dying

[michael.cser20]

My green slimer just started to die a couple days ago. The grren turn to a white patch on its base and the pylops and its side up to the tip. All water parimeters are the same and nothing changed. Alk 7.7
Calc 380
Mag 1400
Ph 8.1-8.3
Temp 79
P04 0
Nitrate 0
Amm, nitrite 0

Alk swing?
Water change/RODI?
Carbon change?
GFO change?
Tank age/maturity?

Did it get stung by something?

Rodi water. 20% biweekly. Bo gfo. Carbon charged 2 last week and tank is around 6 months old. It was growing great and now its going. All my other sps are fine

Not possible

Is bo GFO supposed to be "no?"

So couple thoughts, assuming no Alk swing, even seemingly small can be harmful. The first is that your tank is young and immature like an infant. I don't understand the biology but tank maturity matters especially to acros and millis. It actually took about two years for me to have steady and consistent success with sps. Keeping them alive a few months no big deal but they eventually whithard away. My second thought is that your nutrients may be too low. What strategy are you using to obtain Phos and nitrate of 0? Many on this site strive for ULNS but find they must add nutrients back to the system. Phos and nitrate play a role in the biochemistry and health of the tank and coral.

Yes thats a no for gfo. And i understand. When in doubt, wait it out. Time will make it better. The weird thing is i have a feag of the same coral from the same poece 5 inches to the back on the frg rack and its growing great

+1 on too low in the nutrients. I would get a measurable level of NO3 and PO4 and see if that helps. You can dose spectracide stump remover for nitrate and NeoPhos for phosphate. I would get NO3 to 1ppm and PO4 around 0.04ppm - something you can measure. I killed a lot of acro before I figured this out.

I have small patches of hair algea and my cheato grows so dosent that mean i have nutritients.

 

[samba_dad]

Yes it should. Have you started carbon dosing or using bio pellets recently? Try measuring your alkalinity every day at the same time with a good quality test kit (I use the Hannah) to see if you notice any swings.

Add amino acid to feed your nitrates. If you don't have amino feed a little extra.You want some nitrates and no phosphate.

I bet it's in a path of direct flow.
SPS don't like constant direct flow.
As you mentioned all other SPS are doing fine and no change as of yet.
Maybe moving it to a different spot and wait it out.
