First off, there are VERY FEW LFSs that actually know much about keeping/treating seahorses so I'd be VERY leary of any advice they might give for seahorses. There ARE however, many that CLAIM they do and some of those actually believe they do, even though their knowledge is far less than many regular hobbyists.
I can't actually recommend that particular treatment as in my 18 years of seahorse keeping I've NEVER seen or heard of it being used for seahorses. It doesn't even kill flukes which are common.
Normal treatment for seahorses with parasites would be to use formalin which you can order from amazon. The instructions are on that page I referenced re meds/dosing.
If someone actually HAS used that med successfully on seahorses, hopefully they will chime in here.
