Had a zoa frag melt.. Dang

[Nano]

All my parameters are great finally! no pox or nudis/spiders that I can see, but one of my frags melted over the past couple of days, I've made some phone calls, and poked around online and alot of people are swearing by Furan-2 for reviving zoo's and curing them off illness etc. plus a lot of people are reporting explosions in growth after dipping, now me being new, I am just looking for that extra comfirmation from you guys! as I know there are a lot of "Zoaholics" on here like myself! Thanks for the help guys!
