I messed up. Coral dip help.

[Jaag]

So I had a bunch of flatworms in my 10 gallon tank. I mean a bunch. I treated them with Salifert Flatworm Exit. I sucked out worms before I treated and after. I sucked all my sand, blew my rocks off sucked up what came off of the rocks etc. So during all this all my corals (mostly softies, a few LPS, zoos and a rainbow nem) all were looking just fine. I did a big water change and I wake up the next morning and everything looked like crap. I waited a day and everything was on the downhill. I don't know what I did wrong.
My last resort was to put my stuff into my friends (a good friend) tank. I did just that and about instantly everything started to look happier. I am just a little bit worried because he has some aiptasia and majano.

I hooked up a big carbon reactor (for up to 300 gallons) and I am going to let that run for a week before adding anything to my tank. I just have the rock, sand, a toadstool and a couple mangroves in the tank.

So here is my question. Once I get my corals back I want to really make sure no unwanted pests are on any of my corals and get into my tank. What should I do to make sure of this? I want to know what coral dip you think. I am thinking Bayer. I know people are going to tell me to QT but that is not an option for me right now.

I would really appreciate help. Thanks guys.
Here is my tank before the "crash"

Bayer works well, it'll get all the adult parasites off, i use revive and or an iodine based dip.. all of them should work well imo have you seen the brs video to coral dipping?

I have watched them all. They are awesome. Will Bayer kill aiptasia and majano? Also I have heard (don't know) that Bayer doesn't kill algeas

hmmm thats tricky, I've never tried the dip on aiptasia or mojanos the only thing i can tell you will kill them is aiptasia x by red sea.. thats a product I've used and im sure other brands work too.. as for algaes i haven't noticed much algae death when i dip with iodine or revive my clean up crew usually takes care of it but that would be interesting to know if bayer kills algae
