SPS white areas

[Quoc Vu]

Hi

I need some help . I can’t figure out why my Walt Disney is getting these white areas? Its turns white but doesn’t spread or die. It happen before smaller patches then grows back . My Mag has been consistently low I am trying to raise it slowly. Any feedback is greatly appreciated .

Alk 10.2
Cal 430
Mag 1150
Temp 77.5

There’s a million reason why you could be having tissue necrosis. You need to provide every detail about your system for a chance at being pointed in the right directions. Because of testing errors an and deviations, an ICP test is really a necessity here.

Will look into getting an ICP .

I’d love to know why this happens too.

I recently got an ATI ICP test, and my score came back at 80%. The missing 20% was mostly due to elements like manganese and potassium. Interestingly, ICP tests don’t seem to like high alkalinity — they want it around 8.

That said, one of my acros developed a white spot that eventually spread across the whole colony. Now my rainbow milli is starting to show a white spot as well.

Everything else in the tank looks fine, which makes this even more confusing.

My Walt Disney now has no poly extensions.

I am going to switch away from Reef Crystals to a salt with an Alk at 8.

I use Reef Crystals too. I never thought about the salt but I been starting RC around the same time these issues happen. But I can’t say it’s the cause without proof.

Without an ICP test. Here are my details I can think of.

150 gal Planet tank
3 hydra 64 run at 50% - 2 OR4 run at 80%
Orbit 4 and orbit 2 for flow
I dose Kalk approx 900 mL a day
I have mix reef with my LPS are fine .
This WD and a large Bill Murry are only 2 that are having this issue. It doesn’t spread or get any bigger . I just switch to reef crystals approx a month ago . So far two 30 gal water changes with it . Thats all the relevant info I can think of . If all you can say is get an ICP then thank you anyways but I didn’t get one yet. Thanks .

How long is the tank running? How long have you had the WD growing? Any idea on par levels?
Alkalinity?
Phosphate?
Nitrate?

Are the white areas shaded? I doubt it has anything to do with your magnesium.

My Walt Disney has lost a lot of tissue. The tank went through a rough patch this year and the WD did not take it well. It is probably the most temperamental acro I have. Look at all the dead tissue at the base.

Tank been up for 8 years. I had the WD for 2 years from small a plug .
Alk has been constant at 10.2 to 10.5 I test pretty often .
Phosphate I use use Red Sea test and always get a zero reading. I try to feed a ton with still zero.
Nitrate is always very low too max is 2ppm.
I been in hobby a very long time and never had this issue before. I have always used tropic marin salt but recently change to Reef crystals since I read so many people use it just fine . Maybe I shouldnt have changed but I refuse to blame the salt.

It's shaded areas. All of the tissue loss in where the natural shadow is.

No. thx for asking but I think I put it in a great spot it gets light from many angles. One of my favorites sps so I try take extra good care of that piece.

I will definetly take a closer look during peak like light times.

Also - how close is the colony to a powerhead and at what strength if there is one close? Those big chunky areas are a big sail and flow can really hit them hard.

Crazy thing about this issue that I forgot to mention is that it will turn white then after few weeks it heals back in that white area and doesn’t die or turn brown. It’s almost like it got burnt or something then heals .

Classic stn. It just happens sometimes without any real explanation. Same thing happened to my WD.
I have 2 small pieces that survived fragging and are encrusting.
Everthing else in the system looks good.

Thx for sharing . I am not new to reefing at all been doing it for 20+ years. In the past my stuff would turn white and go thru the entire colony and die . This is first time I had it just get small random patches then heal . I will read up more on this . Just like to hear input on this since I feel my tank is actually healthy. But of course it’s not if this happen.

 

[jackson6745]

Has your PH been dipping very low recently in the middle of the night? Many times when I get tissue necrosis out of the blue when the acros have been otherwise thriving, it usually occurs overnight when ph dips more than usual. With heatwaves and higher co2 in the home, the ph drop can be significantly more. Just a thought.

YW. Been in the hobby 30+.
I believe it's bacterial but no one really knows why a otherwise healthy coral decides to die.
Any disco mushrooms in the system?I have had them release and land on acros. Could not figure it out until I saw one clinging to a stag.
Let us know any thing you find.

I think my PH is pretty steady . I know it’s on the hi end but it’s very stable. Would constant hi PH cause it?

So much for the low ph theory!! lol.
If that probe is calibrated and correct that’s certainly higher than what is a recommended safe zone. I personally never ran my ph above 8.65 so I am not sure if this would kill corals. I read that it could…
