My 120 prob has 145 total water volume. I had this stuff come in a year or so ago and it’s completely taken over a rock my HW and a few other nice high end sps colony’s reside. I’ve pulled the rock and scrubbed and dipped in various things before and the attempt was futile. It’s now started to spread to other rocks and is in the process of a take over. It’s over growing some of the frag plugs I gave and I Jst want it gone. As I should be, I’m extremely uncomfortable running any foreign chemical in a reeftank and especially this one. I have a ton of high end sps in there. I got a packet of this stuff, Fembendazole, and have been told it’s very effective. Does anyone have any experience with this stuff? The pic shows a portion of this stuff up on my HW colony. Please provide feedback
