All-Blue is a traditional formulation used for the prevention of the most common fungal and parasitic infectious diseases that affect aquarium fish.


All-blue is a stabilized solution of 2.0% Methylene Blue added with small amounts of formaldehyde and a powerful antifungal agent. Product stability is guaranteed for a minimum period of 5 years.


Methylene Blue solutions have long been a traditional remedy against some of the most common parasitic diseases (Trichodiniasis, Epistiliosis, Chilodonelas and Costia) and against opportunistic fungal infections, such as those of the Saprolegnia genera.


Although the therapeutic efficiency of Methylene Blue is not all that we would like it to be, it has the advantage that its low toxicity allows us to apply it at high doses with a good safety margin. 


As a preventive:


Apply 1 drop of All-Blue for every 2 liters of water. Recommended every time you log in  new organisms to the aquarium.


As a therapeutic:


Separate the sick fish into a small aquarium  and add 1 to 2 drops of All-Blue for each  liter for 5 days.
