Coral Tumors or bubbles ...

[Paulooliveira]

hi Mates ...

anyone see something like this ???
the colors are fine and they show some grow but with this strange form ...













hope you can help ...

Please list your water chemistry with Magnesium included.

There have been a number of threads on forums over the years regarding this issue. Some feel it might be viral and others contribute it to chronically high magnesium or calcium values.

Hi ... nothing of this ...

My chemistry

Ca-430
Mg-1275
Kh-7.7
No3 - 1
Po4- 0.03
Salinity 1.024
Temperarure 25.5°C

Forgot k+ 390 ...

I see the other topics but no one have a "conclusion" ... the strange thing is my chemistry is always stable ...

I had this happen to me once when I overdosed Calcium. It eventually went away on its own, but it did take a while.

 

[Paulooliveira]

My calcium today are at 420 ... and the every day i got more tumors ... in 2 months almost all corals are afected , and calcium keeps at 430 / 420 ..

 

[Tahoe61]

Maybe let the calcium wander back down to 350 and see if the issue turns around. How are you maintaining those values?

 

[Paulooliveira]

i will try ..
i keet the values with balling light from Fauna marin , at the moment without traces ..

the strange thing is some corals grow well for the side and on the top get this tumors ... see this picture ... dont look suspension particles , im cleaning the glasses at the picture moment ..



this is the strange thing ... and let me thinking that is some light problem , ag 6months i change the 2 aquablue Special for 2 Coral Plus , now my bulb setup is

Blue plus
Coral Plus
Blue plus
Purple Plus
Blue Plus
Blue Plus
Coral Plus
Blue Plus

i really dont know what is this ,last night i buy new tests for calcium and Magnesium, and the values are the same as old ones ... but i will try down the calcium ...

I had this happen a long time ago. I never found out what caused it. This was in a ULN tank with little feeding, and I did dose kalk and vinegar at the time. Not sure if that anything to do with it….

 

[Tahoe61]

How long is your lighting period?

 

[Paulooliveira]

Start with 2x80w 2 hours ... next 8 x 80w more 8 hours and end with more 2 hours of 2x80w

I'd reduce the photo period down to 8-10 hours.

 

[Paulooliveira]

Ok .. i will try it too ...

the strange thing here is , not have a coral type , not only deep waters , i have in montiporas , in echinatas ... in diferent places of aquarium ...

and the bubbles gone alone ??? im crazzy because every day i have more ...

I have a similar issue but only on a couple of corals ( Hawkins Echinata and a small spot on a Red Planet Acro) I have done some research and have heard the high Calcium and Magnesium theory which doesnt apply in my case. Any thread I find on the subject ends with no determined cause. My Hawkins looked very similar to the Acro in your first pic but the new growth has improved a little bit.

Your case is much more extreme than mine but one similarity I notice is I run almost the exact same lighting as yours except mine is an 8x24Watt ATI Sunpower but pretty much the same bulb configuration. wonder if it could be related to lighting?

Yep, they eventually went away. No idea what caused it. If you search this, many other have experienced the same thing. All kinds of speculation, the usual scapegoats get throw out there, but no real cause has been determined.

 

[Paulooliveira]

yes no real causes ... Jimbo , My calcium its 430 at almost 1 year , and magnesium 1275 ... for this 2 values i think is not the problem ... i will try to change the bulbs , but im really confused , i cant find anything ....

 

[WrongGenotype]

I have a chalice that did this. I've had it for about two years and it's been there the whole time. It was popped once and came back a month or so later. Here she is.

 

[jackson6745]

Sell it as a bounce chalice :D

I've seen LPS develop bubbles in the tissue from being over-lit, hence was the rationale I had behind suggesting to reduce the photo-period. You may have just provided a stronger case for such.
