Whats this in my Refugium

See quite a few of these but only in the refugium so far. Was just hoping that someone knew and advised if not beneficial. Thank you.

Hi,

These are hydroids. They are common in new tanks, but usually go away on their own.

Thank you. Tank is only a month old so makes perfect sense.
