Hydroids?

[sailor4life]

Hey there, so ive had this (confirmed) hydroid issue going on for roughly a year now. It has affected some of my corals causing them to melt or stay closed. I've read multiple forums saying lynx or fringback nudis will eat them but as they are not available since 2018 I'm left with resorting to other options. unfortunately i cannot tank of the rocks and treat them their self due to my rock structure being 3 main rocks covered in coral. I've read that you can use Fenbendazole. I Just haven't found any set of instructions or specific type of medication to buy to use. Any help would be great!
