Frag pests help and tips please

Ok so recently i've noticed my normally open and happy zoa frags have been closing more often. I started wondering about pests even though i dip everything before i put it in my tank. I've been using Revive as my dip and maybe that isn't effective enough. I think one mistake ive made is allowing frag plugs from other tanks to enter my tank. In the future Ill remove the frag and put it on a brand new plug. Moving on though... A couple things ive seen but im not seasoned enough to know for sure if they're pests so any input is appreciated. When i pulled the plugs out and removed them and dipped I found a decent amount of these tiny thin reddish worms.. Any idea on these im just assuming they're not good. Another thing ive noticed on quite a few plugs and these little white kind of spiral shaped hard bits. I dont know if these are nudibranch eggs? The pics online show them as little spirals with dots but maybe this is just under extreme magnification. Another thought is they might be vermitted snails. Would these be something to actually worry about if thats the case? Aside from identifying these two pests ive mentioned do you think removing the old plugs and attaching them to new plugs is enough? meaning are these pests elsewhere in my tank? Im running bare bottom tank and using acrylic frag racks. I guess they could also be in my sump but thats a bit more difficult to determine. Im just hoping what ive done is going to be enough. Im ok with dipping in the future if i need to get rid of any stragglers but im open to suggestions for what i can do now.

Sorry about the picture quality. You can see one of them pretty well in the green algae bits. Thank you for your earlier reply. As far as dipping should i keep it up and do it once a week so i don't stress them out? I just want to make sure things don't get out of control but i don't want to lose a bunch of healthy ones while trying to remove bugs. I've got a 6 line that i had hoped would get rid of some of these things but im not sure if that's happening. One thing I've noticed lately is a ton of what i think are pineapple sponges. I had a lot in my sump but they're all over the frag racks and on some plugs. I don't think i need to worry about those though do it?

Ok great news :) I've just used revive as a dip so far. Actually used Hydrogen Peroxide on a few last time as well. Maybe ill give them another week and try the Bayer dip. I've read lots of good reviews on that I was just a bit hesitant to use it if i didn't have to. Im glad to hear about the sponges I was just surprised to see them kind of explode overnight in the display it seems. 

I exclusively use Bayer and it does a phenomenal job. I do complete 2 separate rinses after the dip to ensure all critters get blow off and no Bayer makes it to my tanks. I have never lost a fish or invert at anytime after using Bayer.
