The cephalexin seems gentler on the zoas (bonus in that it's also NOT a suspected human carcinogen) and completely knocked out the pox in my tank 2 years ago and counting... I kept having recurrences with the Furan-2 regimen, despite no post-treatment new additions during that time.
In either case... make your dip with used tank water instead of fresh/new saltwater - saves you a whooooole lotta temp/ph/alkalinity matching and lessens the shock on the treated zoanthids. And continue the dips for at least a day or two after the pox seem to clear.
