trachyphyllia frag dying

[Andrew2255]

So IV had this frag for around a month 2 months now. Recently it's started to look strange with some white marks around it.

Would love

Any opinions or advice

Do you have any fish in the tank.? Parameters? Other coral near it?

 

[Andrew2255]

Yeah tested today and everything seems ok

Calcium 450

What is your Alk and phosphates at?

 

[alton]

What is your lighting level? My wellso’s do great around 200 par

 

[Andrew2255]

What is your Alk and phosphates at?

Alkalinity 2.86

Haven't checked phosphates for a while could be that

Although everything else in tank seems to be quiet happy

 

[Dolelo96]

2.86? That is extremely low. Should at least be 8

 

[Dolelo96]

I keep mine between 8-8.4

Maybe I tested it wrong will check again shortly if not there's my problem

I think he's using PPM rather than DkH

EDIT-I meant he's using Meq/liter rather than Dkh

 

[Dolelo96]

Absolutely! My trachy is very sensitive to salinity & alkalinity changes. When he doesn’t look good that is the first thing I check

Never mind alkalinity is around 8 salt is .25

 

[Rakie]

phosphates are crucially important. Especially for LPS.

Ok that's better. The 2 got me worried . Do you test Alk regularly? Do you have a baseline for Alk? Have you done anything recently like a large water change or Alk additive? Large Alk swings will not make corals happy.

Will need to test Phosphates if not already. 0 phosphates causes my LPS to close up.

What's your PH?
