Hey
@alimac122
here’s information I pulled from humblefish and Big G. I realize you are dosing your display. It doesn’t affect biofilter or inverts except tube worms, feather worms, bristleworms. If you have a lot of those, it could cause an ammonia spike. Also note that wrasses are considered sensitive to praziquantel.
From humblefish: note the water change time and use of carbon
If you are treating a known prazi sensitive species (e.g. wrasse), you can run carbon or perform a water change 24 hours after dosing in order to limit exposure time. While praziquantel does remain active in the water column for up to 72 hours, only 24 hours are needed for it to eradicate external worms. Don’t forget to still do the second round though!
from big g.
PraziPro works best in a QT with a longer soak time. Prazi remains very active in the QT for 24 hours or so and then declines rapidly. And in that QT, highly recommend using a powerhead aimed up at the surface with it actively rippling the water to compensate for the O2 the oxybispropanol is absorbing/using.
Dose the Prazi. Wait 5-7 days. Then do a 25% water change. Dose again. Wait 5-7 days. Then do a 25% water change. Then observe for 10 days. We've seen prazi resistant flukes lately
