check parameters and your salanity lvs of your tank.

[ashaegyee]

salty is 1.026 but kh is 11 high try to lower down

zooxanthellae left the coral.

Check water params and temperature.

[hotsoup]

look like STN to me

Bro, trim the STN portion away or frag them to prevent further spread.. must act fast before RTN.

Two most common reason why SPS stn. Wrong water parameter and pest or disease infection.

Suggest you get a reliable test kit and test for your tank water parameter such as KH level. If possible test for ca and mg as well. Salinity should also be checked with a working refractometer.

Try to recall if you have done anything new to your tank ( such as adding carbon, additives etc ), if so, preferable stop adding if possible for the mean time.

The best possible solution to solve the issue is to do gradual water change with a reliable salt mix...say about 10-25% depends on the severity of the STN. You might need to perform water change for two to three times so as to bring the water parameters back to a normal level.

There are many reasons as to why your sps is having stn, if you find out the water parameters, you can narrow down the cause and solve the issue more effectively.

Turning white tip down or bottom up?

[ben loh]

I also having similar issue but mine is bitter up..

[james72]

Top down could be kH high, too high flow,

Bottom.up could be pH swing, lack of flow, pest.....etc

[ben loh]

thanks, will monitor the progess..
