Help Coral Blisters??

[spykes]

my water parameter is
9-10DKH of alk
1290PPM of MG
450 of CA
SG 1.024

every since i started my tank, my corals started forming blisters on the end of the tips. I dont know why, but i've readed the previous thread and found out low MG would do this to you, but my mg is at a good level. why do this do this?

I would definately get your salinity up to about 1.025 - 1.026. Are you using a refractometer?

 

[spykes]

yes i am, al;right i'll bump up the SG even more

 

[joetbs]

Dave, your mg is a little low. Should be 3x the Ca ~1350. I try to keep mine at 1400, everything seems to do better.

[spykes]

cool joe, i'll bump everything up.

while i agree with the recomendations so far, i don't think any of them are the cause for coral blister's. what exactly do they look like? what types of coral are they on?

 

[MiddletonMark]

You mean like these?

 

[spykes]

yeah exactly like that, but instead of one big one, it's alot of tiny ones. my stylo is covered with it.

What coral varieties is it affecting?
What varieties is it not affecting?

How long has it lasted?

Mine only happened to this single Acropora, lasted a few weeks [has happened more than once, though not for quite a while] ... and didn't seem to cause any long-term harm to the coral.

I changed a lot of water, kept things as stable as possible.

 

[spykes]

granulosa, gomzei, echinta, yongei, and losettee. it has stayed this way since i started, it isnt a single acro that is doing this, majority of my acros as doing this. my SG is now 1.026

According to Borneman it is normal. I had that happen a few year's ago.

 

[spykes]

normal for what? alot of my corals have it, mainly the aquacultures i got from atlantisaquarium

 

[atzak]

have you ever fragged one off and split it open. I'm curious what's going on inside

 

[GreshamH]

I recently sent Eric Borneman some pics of this condition, and heres a few quotes from that email conversation:

looks like you have a tissue-skeletal anomaly that has been presented as a type of coral neoplasia that is relatively common in Acroporids

Basically, the areas affected are not usually reproductive and you may see some local loss of tissue with a hard nodule formed, but the colony integrity is typically maintained.

I wouldn't say this is very common in our reef tanks. There must be some specific water parameter causing this....not that I know what it is

Found this thread through a google search.

What do you all think of these? Is it similar?

I'm into my second water change with ESV B-Ionic. In total I've changed out around 90 gallons of my 165 gallon total system volume over 4 weeks.

Nitrates are reading 4 PPM.
Salinity around 34 PPT
Phosphates are around 0.04 PPM
Ca at 470 PPM
kH at 3.4 meq/l
Mg at 1340 PPM

last time that happened, I lost every pieces that did that...

 

[Ted_C]

Yep - I have already lost around $1500 worth (30 frags or so). Its affecting Monti's, milli's, Pocilliporas, Acro's, Scroll (or Pagoda's Cup), Pectina, Hidden Cup Coral and a stylophora too.

Following. Never seen this before
