Methylene Blue is effective against superficial fungal infections of fishes. The drug may be used as an alternative to Malachite Green for the control of fungus when it is known that the fish to be treated are sensitive. Methylene Blue is safe for use with fish eggs and fry for the prevention of fungal infections. As a secondary use, it is effective against some external protozoans, such as Ichthyophthirius (Ich), Chilodonella and Costia.

The properties of the drug as an oxygen transporter (it converts methemoglobin to the normal oxygen carrying component of fish blood, hemoglobin) allow it to be used in the treatment of known cyanide and nitrite poisoning of aquarium fishes. It has been suggested that newly arrived marine fish placed in Methylene Blue can have their survival rate increased as Methylene Blue aids in the reversal of nitrite and/or cyanide poisoning.

The following brief summary of clinical signs often associated with the parasitic protozoans discussed above is intended only as an aid for the beginning aquarist. It is not to be thought of as a definitive diagnostic key. It is also important that the aquarist consult appropriate, accurate references for more specific information regarding disease problems of fishes. In addition, if possible, skin and/or gill smears should be made and examined by a qualified fish diagnostician. Microscopic examination is recommended and is always essential for confirmation of a particular disease. In the clinical signs indicated below, a particular description may be followed by a specific disease causing organism in brackets. This indicates that there is a high probability that the cause of the disease you may observe on the fish is the organism indicated in the brackets. It should be qualified that different clinical signs can be seen during the disease process and that these can occur as the result of more than one disease causing organism.

Clinical Signs
Increased respiration; loss of normal body color; presence of discrete white spots (freshwater or marine Ich); scratching on tank bottom or on objects; lethargic behavior; white tufts or strands on body [Fungus]; dustlike "peppered" spots on body surface, having a yellowish cast [Oodinium].

Contains zinc free, chloride salt of Methylene Blue. Provided as a 2.303% water solution.

The therapeutic action of Methylene Blue on bacteria and other parasites is probably due to its binding with cytoplasmic structures within the cell and also its interference with oxidation reduction processes.

Methylene Blue is stable indefinitely in the 2.303% solution. Aqueous solutions show very little, if any, decomposition even when exposed to sunlight.

Methylene Blue is not indicated for the treatment of Oodinium, bacterial infections, flukes (monogenetic trematodes) or for moderately-severe to severe fungal infections. It is not indicated for use as a net disinfectant or sterilizer.

The use of Methylene Blue is primarily for the control of fungus on eggs, and to assist the transport of oxygen in fish poisoned by cyanide and nitrite ion. Secondary uses are for the control of some external protozoan parasites of fishes. Methylene Blue is an alternative for treatment with other medications when prevailing factors preclude the use of another medication.

This product should not be used in recirculation systems that utilize biological filtration. Methylene Blue will interfere with the normal biological processes of nitrifying filter bacteria. Methylene Blue can also interfere with normal plant growth.

Methylene Blue has a wide safety margin and is nontoxic when used as recommended. Fishes tolerate relatively high dosages without side effects.

The following procedures are suggested for freshwater and marine aquariums and ponds. Methylene Blue is removed by activated carbon filtration. It will also be absorbed by porous materials such as rock, coral and wood. The product is best used in bare aquariums or ponds, especially if they are new. Methylene Blue may permanently color the silicone sealant in aquariums. At the conclusion of all treatments, a partial or complete water change should be made and activated carbon replaced in the filter.

But rather recommended to be used in quarantine tanks or as dip.
