Treating fish parasites usually means picking between something that works and something that won't wreck your biological filtration in the process - PraziPro is built to do both.
Why Biofilter-Safe Matters
Many parasite treatments come with warnings about disrupting beneficial bacteria, forcing a choice between treating the fish and risking an ammonia spike from a damaged biofilter. Liquid PraziPro is a ready-to-use concentrate for controlling parasites in ponds and freshwater or marine aquariums, working without disrupting biological filtration.
What It Treats
- Internal and external parasites across freshwater and marine aquariums.
- Pond parasites, extending beyond just aquarium use.
- Common flukes and worms that PraziPro is specifically formulated to target.
How to Use It
- Follow dosing instructions based on your tank or pond volume rather than estimating.
- Complete the full treatment course rather than stopping once symptoms appear to improve.
- Remove carbon filtration during treatment, since activated carbon will strip medication from the water before it can work.
