Does anyone know if Paragaurd will crash a cycle?
I just ordered this.
KanaPlex™ is a blended kanamycin based medication that safely and effectively treats several fungal, and bacterial fish diseases (dropsy, popeye, fin/tail rot, septicemica). Because it is absorbed by fish it is useful in treating internal infections in those situations where food is refused. It does not adversely affect the filter bed and is easily removed with carbon. To enhance palatability use with GarlicGuard™. Food may be refrozen. For use in freshwater or marine aquaria.
Directions Use 1 level spoonful (180 mg) for every 20 L (5 gallons). Repeat every 2 days as required up to a maximum of 3 doses. Turn off UV, ozone, and chemical filtration. To feed, blend 1 measure with about 1 tablespoon of frozen food paste. Food may be refrozen.
Active ingredients: kanamycin sulfate (40%). Inactive ingredients: potassium sulfate (60%)
Types of Infection Treated: Fungal and Bacterial
Hopefully it'll fare better than other things I've tried - if this is bacterial. If it's not, then I need something for parasites (and I can't seem to find De-Los in any size other than massive.)
