Green branching id and help

[new_world_disor]

Hi all. Had this around 2 weeks now. And all of a sudden its looking pretty sorry for itself and is bleaching a bit, looking a bit patchy. Was a really vibramt green when i got it. I got it with a birds nest and torch which are both doing well. Not 100% sure what it is. So an ID would be good. And any advice on it?

Montipora Digitata....

 

[new_world_disor]

Thought so, any ideas as to why the sudden change?

 

[new_world_disor]

Just done full water tests.... As follows:

Temp - 25.9*c
Salanity - 1.028
Ph - 8.0
Nitrite - 0.0p
Nitrate - 0.0p
Phosphate - 0.03
Ammonia - 0.25
Calcium - 500
Magnesium - 1500
Alkalinity - 9.6dkh

Added some phosban. This was just after a water change

ammonia should not be there. mag's high, cal is high, sg is high.

sorry to say that its a goner.

 

[new_world_disor]

Surely having high Calcium wont causw any detrimental effects?

Salanity has now been lowered to 1.026. Atu had moved causing the high sg. Ammonia is still there. About the same. Not sure how to lower it

 

[reefbroao]

how old is the tank?

 

[new_world_disor]

Approx 6 months . Stock was transfered from An older tank. Everything else is Ok, montis, birds nest, stylo as well as all the lps and softies. The tissue is slowly re-colouring on this coral.

Doing weekly 10% water changes as well as dosing tropic marin balling salts. Seeing good growth on all other corals.

 

[reefbroao]

Hmm, ammonia is indicative of a problem. Someone else may know for sure.

 

[new_world_disor]

Its possible ive lost a fish (leopard wrasse) but i dont know if it's hiding or died to be honest, no way of telling. Not had Ammonia show up in my tanks for the last year, till week before last (after that coral was introduced)

 

[reefbroao]

Try placing this elsewhere to see if their is a positive reaction.

 

[Flightdeck]

try moving it to lower light, and flow.

Digi's will react quickly to chemistry changes. Sometimes mine give indicators even before acros will. usually alk swings will cause this kind of reaction, but I'd never want to expose these to any level of ammonia. I have mine under really high LED light but acclimating it to that took quite some time. Usually they will bounce back if parameters are kept stable. I run a calcium reactor and ato.

 

[new_world_disor]

Bit miffed. Moved this and cut the really bad bits off. It was doing really well, growing and great polyp extension. But i think sum1 is nipping at it now.

High calcium can 100% cause problems, especially if alkalinity isn't lined up with it. With your pH level, I'd aim for 400-420 calcium w/ 9.0-9.5 dkh.

Do you use a doser? I had this problem recently and it was mostly due to my parameters swinging rapidly with manual dosing. My 2-part doser is now on the way, so hoping that helps me keep everything consistent.

Yeh i dose tropic marin balling salts abc. Set very low around 2ml every other day. Showing stable results. Ill test ph tomorrow. Was fine last week. And calcium, i need to get a new test kit as minr ALWAYS says 1500+

Just be sure to try and get your calcium a bit lowerr. The balance of Alk and Calc is what allows corals to grow and with Low Alk and High calc, you're going to have STN (which is what looks like is happening to your coral). Your mag is also a little high, but that should be ok. Focus on getting calcium around 410 ppm and see what the results are.
