Aquasonic Methylene Blue solution is most promisingly used as a preventative against fungal and bacterial influence on freshwater fish eggs.

Sometimes suggested as a treatment for ich, velvet, Cryptocaryon, Amyloodinium, other protozoa, monogenetic trematodes, Methylene blue is far less poisonous than malachite green and formalin but also not as effective against active infections.

Note: Remove active carbon before treating aquarium.
