I had a tank going for a few months.. Hydroids took over and THEN I ordered panacure. Also suspected nematodes.. You are probably going to need to treat for hydroids. Panacure is the go-to. It will kill off many inverts however and leach from substrate for a LONG time. Available from DanU. I hope I'm allowed to post the site- seahorsesource.com. I got my dwarfs from an online retailer as well, wild caught and relatively cheap. I QT'd everyone in a methylene blue and formalin solution- except my male gave birth in QT and I transferred them right over. So if I did get nematodes it must have come from them. I just started cycling a fluval v as well. Saw this thread and picked one up from craigslist. I was going to do a nano reef after upgrading lighting, but you've got me motivated to try dwarves agains! I'm also in Orlando. What LFS did you go to?
