Is this RTN

[Haksar]

Would like to know if below acro has RTN'd.If so what should I do to save it.
Coral was given to me from a LFS to save it.Is this bleached out.The coral I am referring to is on the left side closest to the camera.
Any help would be appreciated.

If it started from the bottom and got to where it looks now in 12 to 24 hours then yes, RTN. Looks like a goner now. You could frag off the tip that has a little color left and see if it will come back.

I would have to say it has RTNed.

Thanks as per my friend it took 3-4 days to reach this state

all your sps look browned out. the others will be gone as well, if you dont get your water in check...

 

[Haksar]

Yes I know but I have had issues with a nuisance crab eating the skin of my various SPS.
Although they look browned out but I have had decent growth.Presently my parameters are stable but I am working on it.Thanks for the feedback.

looks as though some neighboring corals are also receding from the base up... Sorry, but I would do some testing immediately and get your water in proper range if that is the culprit... Could also be pest related, turkey baste them at night, if you have AEFW, you will see them using background/ambient light or a flashlight... Good luck, I hope things get on track...

 

[Haksar]

Thanks plyle02.I will turkey baste them and see.

Both the coral on the left and on the right are dead. If your going to look for aefw it's best to do in a white bucket or container. That way you can see what comes off and it doesn't just dissapear back into the tank.

Thanks 29reef.The coral on the right is having PE but is slowly making a comeback.
I am having issues with crabs and my tomato clown munching on these SPS and I am losing color and tips.I need to DIY a crab/fish trap.Do you have any idea.I have made one but the bottle is not sinking.

With all due respect crabs chewing ur acros don't make them brown like most of yours. Could be old lighting or water quality. I'd check both. Your corraline is spectacular though. Your doin something right. Cheers

Out of curiousity, what lights are you running Haskar?

Def RTN

Looks to me like the typical led brown out tank.

 

[Haksar]

I am running LEDs.My water params are as below,
KH -9
Cal -460
Mag - 1440
Po4 - undetectable (using API test kit)
No3 - undetectable (using sera test kit)

I am also doing vodka(2.8ml-this is my sweet spot) and vinegar (28ml)

The reason for mentioning the crabs is because my blue milli and yellow acro had lost its skin and now its slowly recovering.

 

[flyin2jz]

I figured it prolly was. I've seen very few led tanks that have great colors. I believe it's not because of the lack of light but too much light and this causes the brownout look. I've seen people keep colors for a little while when switching from halides to LEDs but they quickly go brown. Ur water looks good but the led lighting isn't working well in my opinion. U will have guys comin on here saying o they are fine u just need another 500 bux worth of different colored bulbs. Just a waste of money to me and most sps keepers

 

[Haksar]

Thanks flyin2jz.I guess as much but to be be frank with you I was using 02 150 W 20K radium MH and 04 T5 54w ( pair of white and blue) but colors were not good even then.But at that time I was struggling to keep the KH steady and now I have it dialed to perfection with my Korallin Calrx.I must say I have great PE on most of my SPS but its that color I am missing.Should I reduce the feeding.I dont feed much but I feed Zooplanktons and Phytoplanktons every week.Flow is 26,000gph on a 100gallon tank.

Thanks for your feedback and taking time to answer my questions.

 

[schroder_reef]

Could you raise the LEDs to help with the color? I don't know too much about them. What's the wattage of the LEDs?

 

[Haksar]

Thanks schroder reef,this are 03 -240w (80x3w)14k daylight and 40w (1wx40) 460nm light.So in total 720w 14k and 120w 460nm lights.Light timings are below but this are still on trial period.I have noticed with the below timings my Suharsonoi is coloring up slowly.
Rest of them are still brown except my green stag horn/green and orange monti/blue tort and echidna.

13:00 - 15:00 - Actinics
14:00 - 19:00 - 01 LED Day light
15:00 - 18:00 - 02 LED white light
18:00 - 21:00 - Actinics.
