Prazi and Formalin

We are treating a new pair of clowns (Ocellaris, captive bred misbars) in our QT for what I think is brooklynella. I'm not 100% sure it is brook since the signs haven't progressed as rapidly as I have read they will. Long story short, we started w/ a different pair of clowns 3 weeks ago that had genetically deformed mouths (couldn't eat) and did not make it (bad purchase from LFS!). One week later we replaced the clowns with another pair of Ocellaris (CB) that were doing great and had been in the LFS (different one) for about a month. Most unfortunately, we didn't QT, and about a week after being in the DT noticed that one of the clowns was hyperventilating and had some erosion on the fins. I immediately did a freshwater dip for 10 minutes on both clowns, put back in the DT and set up our QT. We also have a LMB in the DT.

Once the QT was set up I did a formalin dip (100ppm for 1 hour) on all 3 fish and transferred to the QT. After 24 hours in the QT, I did another formalin dip and also a bath in the QT at 25ppm. All fish seem to be doing ok. One clown has started eating again. The other hasn't, and has long, stringy white poop. There is still some fin erosion on the clowns. The LMB is doing just fine, but stressed as heck.

So, question #1: Should I also treat with Prazi, given the white, stringy poop? That particular clown is also losing weight, but she hasn't eaten in a few days...
Question #2: Can I treat with Prazi while also doing the formalin bath (25ppm) in the QT? Or, should I wait until I'm done treating for Brook, and then do the Prazi treatment?

Also, I am worried about the LMB as he doesn't eat Nori and there isn't any algae in the QT - I'm guessing I shouldn't put him back in the DT for 6-8 weeks, right, as he could become a carrier for brook? Anyone ever had success with a LMB eating Nori in the QT?

Thanks in advance for your thoughts!!
 
Both praziquantel and formalin can suppress food response, I personally would not combine at the same time.

Also, I used API General Cure (Prazi Metro) for internal flukes, only one episode, but it took care of poop oddities pretty quick, it's lower in praziquantel than just dosing praziquantel. Might want to read up on it.
