Help ID and Solution to rid of it

[tristanfish]

Team: please see picture below.

Some sort of algae? I've scrubbed it once and came back. Seems to be growing on the zoa stalk too so I can't scrub too hard.

Anyone know what they are and how to rid of them safely.

Do you think you could grab a couple more pictures from a different angle? Do you think they could be a species of hydroid?

It reminds me of a bottle brush hydroid. Lemme see if I can find a picture and the scientific name.

I scrubbed them off the second time already. They are difficult to take pics since they are clumped together and pretty brown.

I'm worried about another area in the tank. Which I can't get to nor take pics

The part I circled is the best Rep of these things

Hmmm.... the stalk is too thin. Is the growth pattern similar at all? Like does it go around the stalk of along the sides of the stalk? Does that make sense? Don't mind the color.

What is your Magnesium level?

Not similar with the growth pattern. The picture above looks pretty large. These are more micro ish

I'm not sure, does high or low effect certain algae growth?
