Help with Montipora

[OceanL0ver]

Can anybody tell me what is eating/killing my red Monticap?

Sorry this was the best shot I could get

How long have you had it? Tank params? Any new additions lately?

I've had something similar happen to my montis. What you need to do is pick up the coral and look underneath it. I found that montipora eating nudibranchs were eating them. They are known to come out at night and have a midnight snack on your montipora. If you don't see them under your cap, then I would check your alk.

I’ve had it a year. For six months I had no problems, then it started dying again. I fragged it out and started growing again then started doing this necrosis again. No new additions recently.
35 ppt
500 calcium Red Sea
7 alk Hanna
Mg 1400 (Red Sea)
Nitrate 5 (Red Sea)
Phosphate undectable (Hanna)

If it is nudibranchs how do I get rid of them?

All has been stable forever. Frequently checked and on a dosing pump

I had success picking the coral up and used a bent safety pin and poked each one off into a glass of salt water. I used a tooth brush to remove the eggs that were underneath the cap. They never came back.

My montis are attached to large rocks that I cannot pick up

I have a lime green Monti and emerald green Monti and neither of those two have ever been affected

 

[OceanL0ver]

Ann wrasses that will take care of nudibranchs?

 

[OceanL0ver]

Ok so picking these off is the only way then

 

[Reefltx]

Years ago, I dealt with them using a pipette. I picked them off and the eggs as I see them until I never saw any again.

 

[OceanL0ver]

Thx. I’ve been using a toothbrush to remove the eggs. I don’t know how you guys get to the underside of these playing corals. Mine are encrusted onto huge rocks

You might just try to live with them since they like the aefw are some of the hardest to get rid of.
Try using a mojano wand to zap them.
Just turn on around the coral and they should start to moving around.
I do that with the red flat worms.
You can kill the eggs if you see them with it too.

If you have zero phosphate your montiporas will have problems. It often starts with patches without tissue anywere on the coral.
If you use phosphate remover or killer or organic cole you should take that out. When the phosphate level is up to 0,03 or phosphourus 10 you can begin again with a lower dose.
Montiporas are the most sensitive corals for this. Some acroporas is seemingly not influenced and the other corals is somewhere in between.
The corals will get clearer more filled colors too.

Thanks. I have been running gfo. I’ll let my phosphate slowly increase a bit. Thx
