green birdsnest

[DAN-O]

my green birdsnest has one tip of one branch turning brown in color. i noticed that it is starting to get larger. the rest of the branches are fine.
it is only on the one branch. am i suppose to leave it alone or should i
cut the brown part off so it doesn't continue to spread.

it had died off and it's more then likely algea growing on it

Green birdsnest are pretty hardy.I have a colony and make sure they get plenty of flow.Maybe a phosphate problem?
