HydroPlex is a scientifically developed copper free, antibiotic free, broad spectrum water treatment 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]helminthics and annelids, molds, fungi, yeast and microalgae. HydroPlex is also proven to be effective for the elimination of brown slime due to diatoms, as well as for the control of viral diseases. It is especially effective, and strongly, recommended, in a dip regimen for cleansing new arrivals of unwanted parasites and bacteria, especially if a quarantine tank regimen is not practical. It is very effective for treating diseased fish via a dip regimen or in hospital tanks.
