(a) Obtain two (2) clean glass vials or test tubes, into one (called a standard) add 1 teaspoon of deionized, distilled or clean tap water; into the other add 1 teaspoon of a water sample from the pond or aquarium being treated.(b) Add 1 drop of the 3.84% Permoxyn solution to both tubes. Cap tube and invert a few times to mix.(c) Allow to stand undisturbed up to 24 hours. Depending on the concentration of organics in the sample, a change may be observed within a few hours. The "standard" will remain a transparent purple. The sample will change from purple, to a rose-purple and to brown. If the sample turns from transparent purple (when compared with the standard) to a brown, the amount of organics in the water system can be considered excessive. If the sample remains unchanged, or if there is a slight change, then the organics are low. In the latter case. Permoxyn need not be used.
(a) Remove carbon and clean the outside filter. Return the filter to use without the carbon.(b) Calculate the actual volume of water to be treated, taking into consideration the displacement of water by sand and rock.(c) Add 1 teaspoon (5 mL) of Permoxyn per 10 gallons of water. This produces a concentration of 5 ppm. Do not exceed the recommended dosage.(d) As the organic materials in the water oxidize, the purple color will change to a rose-purple and then to an opaque brown. When the brown color is observed, immediately make a partial water change. Note: it is highly recommended that when the treatment is performed, that additional aeration is always provided especially in ponds. The dissolved oxygen levels should be monitored during the treatment with an accurate test kit. This is especially important in ponds in which excessive algae growth may be present. Discontinue treatment at any time if the fishes are demonstrating undue stress. Kordon`s AmQuel can be added to the water to immediately stop the treatment.(e) After performing a water change, add Kordon`s NovAqua® to condition the newly added water. NovAqua or PolyAqua® will assist in replenishing the slime coat on the fish which may have been removed during treatment. Return high grade activated carbon to the filter.
