Need help with brown stuff on devils hand coral pls

[Jriv86]

I've had it for over a month now no issues. But the other day it had this brown growth coming out of it. It made an indent in one of the fingers. I ended up using a baster to make it come off . Now I'm left with a indent where it used to be. I also have a weird white spear tip coming out of the top of one of the fingers I circled for you guys. And lastly there is brown stringy stuff on the base. I never dipped it before I was afraid of causing unnecessary stress if not needed. Now I'm wondering if it's a batcerial infection . I simply have no idea. If I look at the indent I swear I can see a whole going into the inside of the coral

You alk is a little on the high side, i believe they also like 5 -10 nitrates I've got one also. Not sure what that white point is. Have you tried to blast of the brown stuff? Could be brown algae. Any other corals have it around them ?

Think there was some necrosis on the tip which you blew off. Now there’s a void. Brown stringy stuff could be algae or hydroids. Need better pic.
