HydroPlex is a scientifically developed copper free, antibiotic free, broad spectrum aquarium pharmaceutical that is effective for the control of parasites and microscopic organisms found in aquaria and ornamental ponds including bacteria, ciliated protozoa, dinoflagellates, copepods, small [platy]helminthic and annelids. HydroPlex is especially effective, and strongly, recommended, in a dip regimen for cleansing new arrivals of unwanted parasites and bacteria, especialy if a quarantine tank regimen is not practical. It is very effective for treating diseased fish via a dip regimen or in hospital tanks.
