What is this

[kp33]

What is this and how do I remove it from the wall of my overflow? It’s not something I’ve ever added but it keeps growing it’s the best pic I could get it’s kind brown in color. It’s in my sand on on sone rock as well. Thanks

It looks like zoas/palys, but there's not enough detail/clarity to tell for certain.

Thats a brown zoa. Can come in as hitchiker on live rock. Usually like yellower light around the 7k.

Yeah it’s the only zoa that wants to grow in my tank, how can I remove it especially from the wall of my overflow? I don’t want it in there

Usually can scrape it off. Treating any coral rudely sucks but that stuff is ugly. My lfs near me has a big vat with crazy fish in it under a sky light that receves natural sun and this stuff grows like crazy in there. Its always the ugly ones that thrive.

Make a siphon tube with a stainless steel straw and scrape/siphon out. Handle with care and dispose. Those look like the same type I let grow off a frag of a pretty paly. VERY quick grower, I thought I rid my tank of them a year ago, but noticed a few popping up and spreading.
