Digitate hydroids and some kind of hair algae on zoa frag

[BamaCoastPyrat]

I have a zoa frag with digitate hydroids and with some green strings coming off of them that look like a cross between green hair algae and chaeto. I can pop the frag off the rock and dip it. What is my best bet with the digitate hydroids? I have Coral Rx and hydrogen peroxide on hand but can order whatever is necessary.

I could be wrong here, but you could dip the Zoa and that should be able to get rid of it. I have a link for a website that shows some methods that can get rid of them https://reeftankresource.com/digitate-hydroids-good-or-bad/

I am dealing with this as we speak. I can confirm that coral dip, like Coral RX, does nothing for digitate hydroids. That is what I used. I then did a 2 minute dip in straight Hydrogen Peroxide and that did nothing. I then cut up the frag and I have one digitate hydroid left that I plan to smother in glue.
