Stn with green skeleton

[hijackng]

hi,
some of my sps stn green skeleton since a few months ago. Is this a kind of sps diseases?

and also my green millie had been in my tank for 5 year, it also stn for unknown reason but leaving with a white skeleton. It still had good polyp extension while it stn. only thing I can do is to frag away the stn part....

It looks like algae growth to me.

Have you tried scraping it off?

Check your phosphate levels and consider GFO.

His corals would be brown if there was a phosphate issue, but that definitely looks like algea, or macro algea that has manifested the coral.

That happens with low or fluctuating Alk levels

It can be scrape off.
the funny part is it grow on it immediately after the stn or could it be the green algae advancing causing stn?

thanks. will take note.

algae cannot grow on healtly sps tissue. More times than not the algae will grow at the same rate the coral is dying so it appears as if the algae has something to do with the demise of the coral when in fact it does not.

could it be the bases arent getting enough flow (im an SPS noob but i read that that can happen)
