Most monogeneans are eradicated by 2.0 mg/L praziquantel and then a second dose is required to eliminate any hatchlings before they can lay eggs of their own.
This "calculator" was developed by the Marine Parasitology Laboratory, James Cook University (in Australia) to provide a more accurate way of scheduling the second round of treatment, based on temp & SG of the water: http://marineparasites.com/paratreatmentcal.html
The tool was specifically developed for Neobenedenia sp., by far the most common genus of Capsalid found in saltwater. While other families of flukes do exist (including a few resistant to praziquantel), the odds are very much in your favor that you are dealing with Neobenedenia considering the species of fish (warm water) we typically keep in a home aquarium. Alternative treatments for prazi resistant flukes include:
- Hyposalinity (for 5 days)
- Formalin baths done 2x (1 week apart), with transfer into a sterile QT following each bath to prevent reinfection.
