Anyone know what’s wrong with my Acro?

[stevenlu]

Are these bite marks? Shouldn’t be burnt tips right? I don’t think I have bug. What other outcomes could there be?

Thanks!

You would have the best guess as to if it's bugs/FW, have to look close. Looks like tissue necrosis to me, though.

What could be the cause of tissue necrosis? Nitrate too low?

What type of lights? Maybe it's too much.

Alkalinity above 8 with limited food sources for the acropora. This does not mean Nitrate or Phosphate, but instead is typically the colonized bacteria and micro fauna provided by established food chains within a mature setup.

Radion g4 pro supplement with t5 blue plus

alk is at 9-9.4. should I feed more?

I had a similar issue with my g3 pros on my 57 when trying to raise the intensity too high.

 

[stevenlu]

lights are 17 inches above the water running at 60 percent ab+ 10 hours a day. Too much?

 

[blkhawk10]

Everyones tank is different so I can't say if it's too much or not you'd be the best judge of that. Do you have other sps in the tank and if so how are they doing? Have your lights been at the same intensity the whole time or have you raised them?

yeah rest are doing well.

It might be too much light...so maybe move it lower and see how it starts doing.

Full peak power for 10 hours? No ramps?
Looks like burnt tips. What are your nitrates and phosphates? Are you using gfo or carbon dosing?

I have carbon running but they're from a month ago. I doubt its still working. nitrate at 2 and phophate at 0.04.
1,5 hour ramp up and down. in the middle 5 hours with T5

Activated carbon and carbon dosing are 2 different things. So no vinegar, vodka, or nopox dosing or gfo? 9-9.5 alk is little high for your low nutrients. 7.5 to 8.5 is the sweetspot.

yeah no carbon dosing. I see, I’ll try to get it down and stabilize. Thanks a lot!
