need to treat for internal parasites. Came across 2 different meds, Seachem's PolyGuard -treats water colum every 3 days. The other is called Paracide X ,which must be put into food, freeze,then drop in tank. The tech support person for ParacideX said the ONLY way to treat IP's is by giving it in food, not the water colum, not sure how I would get this powder into the flake food for the small tetras. Does anyone know if this is really the ONLY way to treat ,or can it be done in the water ? Anyone had any experience with either of these meds ? Appreciate any responses ,need to choose one and begin treatment asap. Thanks.
