Green Hydno help

[MellowReefer]

Hope someone can tell me if there's still hope for this green hydno I got about 5 months ago. I'm new to sps but this one was growing really fast and looked great until now. A few weeks ago I noticed it suddenly lost its polyps around the base. The only thing I can think of is that just before I noticed it I was late dosing alk by 9 hours (yes I manually dose every day, going to get a doser). Would that cause it? I don't have an extremely high flow on it, as my tank is mostly LPS, do they need really high flow?

Should I dip it? Try to frag the good parts? Thanks for any advice you can give.

stn from the bottom up is sometimes caused by alk fluctuations. That would be my guess if i had too. But it is not the only reason this happens.

YES. There is still lots of hope for this coral. If there is healthy flesh on a coral, there is always hope. i am currently nursing a seriatopora which had rtn'd down to smaller than a dime, 2D growth on a rock which came from almost the sise of a baseball. 3-4 months ago, smaller than a dime, today, larger than a half dollar with 3 main stalks each with multiple branches and PE and color is fantastic.

Stable conditions is the key. dont mess with it unless you have to. So long as filamentous algae does not move into the white skeleton, you will not have to do anything.

Thanks! So you mean it might grow back over the white part? Or that part will always be bare now? I think algae will grow on it sooner or later if that's the case. There is one tip that became bare a long time ago and algae grows on it and occasionally I see my foxface picking on it.

Also do you think suddenly stronger flow for a minute could have caused this? I have a powerhead I bought that's too strong for my LPS, but when I clean the tank and a few times a week I turn it on for minute or two. The other day I noticed the hydno was all puffed up when it was on.
