What causes the skin on Acropora to look like this? It looks thin and rough.

I have been battling Dino's hence the elevated nutrients. Could it be caused from toxins? I'm doing water changes weekly to maintain trace elements. Rodi is purchased from a local water store. Perhaps Chloramine? I'm kinda at a loss here. Figured keeping parameters in a good range and stable would help, but the acros seem to continue to decline

This happened to me before! On my montipora! I never did find out what it was but to this day my best guess at what it was is too low nutrients in a new tank. Gotta beef up the bacterial colonies. Have you tried dosing benificial bacteria?

I should note that when I went from weekly to every 3 weeks for water changes it went away

It looks spiky right?

Bump in case anyone has some light to shed on this. Figure it maybe common but I see it from time to time on a few of my frags. Dunno if its general stress reaction or what.

 

[NRG1337]

got exactly the same problem on most of my acros! Did you find the answer of causing this?

 

[NRG1337]

or maybe anyone else an idea?
its extremely frustrating seeing your hw, wd and stuff look like crap under good flow, light, nutrient and stable water params. Doing ICPs every 4 weeks

ive got ceramic rocks so these are in my focus

I used to have this problem. It was a combo of low nutrients and low par. I upped both, dramatically, and no more coral plague.

My nutrients were close to zero and my par was around 80-100 when I thought it was around 250. Whoops. Cost me around $1k in frags over two years of trying stuff.

Moral of the story is to get a par meter and check your nutrients at least once a week.

Edit: I also had low iodine on my icp test. Probably from feeding so very little food. I probably quadrupled my feedings and started dosing iodine every once and a while.

thx for your reply, cant be my case.
High nutrients, high PAR :d

What is the par range?

More details about your system would definitely help.

Do yourself a enormous favor and do not drop one cent on another coral until you get an RODI unit and can make your own water! There are many documented cases of crap water ruining a tank. You can’t verify a stores water and it’s usually junk and expensive. An RO unit only costs as much as one high end Acro. You can’t correct a problem like you have until you can control your own water quality.

I would run GAC until dinos are gone to help reduce dino toxins. I don’t know if this is causing you problems or not but dinos wiped out my acros a year or so ago.
