Aquasonic Methylene Blue 100mL – Aquarium Fungal Treatment

Aquasonic Methylene Blue 100mL is an Australian-made aquarium treatment designed to help control superficial fungal infections in freshwater ornamental fish and prevent fungal growth on fish eggs. Containing 12mg/mL of methylene blue, it is a practical treatment for fish quarantine, breeding and selected external disease conditions.

Fungal infections can develop around damaged skin, fins and fish eggs, often appearing as white or grey cotton-like growths. Aquasonic Methylene Blue helps manage susceptible fungal organisms while providing fishkeepers with a useful treatment option for breeding and hospital aquariums.

The convenient 100mL bottle provides enough medication for approximately 400 litres per standard application, making it suitable for smaller aquariums, quarantine tanks and fish breeding setups.

• Supports selected external disease treatments: Also listed by Aquasonic for use against freshwater white spot, although more targeted treatments may be required.
• Useful for hospital tanks: Particularly suited to controlled treatment environments where fish and filtration can be monitored.
• Single active ingredient: Contains methylene blue at 12mg per mL.
• Convenient 100mL bottle: Treats approximately 400 litres at the standard dosage for one application.
• Australian-made: Manufactured by Aquasonic for ornamental aquarium fish care.

What Is Aquasonic Methylene Blue Used For?

Superficial Fungal Infections

Fungal infections can appear as white or grey cotton-like growths, particularly around damaged skin and fins. They may develop following injuries, poor water conditions or other health problems.

Aquasonic Methylene Blue helps control susceptible superficial fungal infections. More serious infections may require further diagnosis and alternative treatment.

Preventing Fungus on Fish Eggs

Methylene blue is commonly used in aquarium breeding to help prevent fungal growth on fish eggs during incubation. Unfertilised or damaged eggs can develop fungal growth that may spread to nearby healthy eggs.

Using the appropriate egg-treatment dosage in a separate hatching container can help reduce fungal growth and improve egg management during breeding.

Always confirm that the intended concentration is suitable for the species being bred.

Freshwater White Spot Support

Aquasonic also lists methylene blue as an aid in the treatment and control of freshwater white spot disease, caused by Ichthyophthirius multifiliis.

However, methylene blue is not necessarily the most effective treatment for an established white spot outbreak. More specific white spot medications may be appropriate depending on the fish species, parasite and aquarium conditions.

How Aquasonic Methylene Blue Works

Methylene blue is a dye-based compound used in ornamental fish treatments. It has activity against certain superficial fungal organisms and is particularly useful in controlled fish egg incubation systems.

Unlike some stronger antiparasitic treatments, methylene blue is often selected for its role in managing mild external fungal problems and preventing fungal growth on eggs.

It is not a general cure for every bacterial, fungal or parasitic disease. Identifying the underlying cause of fish illness remains important.

How to Use Aquasonic Methylene Blue

Always check the directions on the supplied bottle before treatment.

1. Confirm the condition being treated and check aquarium water quality.
2. Calculate the actual volume of water in the aquarium or treatment container.
3. Remove activated carbon or other chemical filtration media that may absorb medication.
4. Maintain strong aeration throughout treatment.
5. Measure the correct dose for the intended application.
6. Add the medication according to the manufacturer's directions.
7. Monitor fish carefully for unusual behaviour or signs of distress.
8. Follow the repeat-treatment instructions printed on the product label.

Standard Freshwater Fish Treatment Dosage

• Dosage: 5mL per 20 litres of aquarium water.
• Coverage: Approximately 400 litres per 100mL bottle for one application.
• Repeat treatment: Follow the supplied bottle instructions. Some published directions specify repeating after three days if necessary.

Preventing Fungus on Fish Eggs

• Published egg-treatment dosage: 1mL per 15 litres.
• Application: Use in a suitable breeding or hatching container where the concentration can be controlled.
• Important: Check the current product label and the requirements of the species being bred before treating eggs.

Important: Treatment coverage represents one application. A complete course may require additional medication depending on the manufacturer's directions and the condition being treated.

Important Treatment Precautions

• Biological filtration: Methylene blue can adversely affect beneficial bacteria in aquarium filters. A separate hospital tank is often preferable.
• Activated carbon: Remove activated carbon during treatment because it can absorb the medication.
• Live aquarium plants: Methylene blue may damage sensitive plants, particularly at excessive concentrations. Avoid treating planted display aquariums where possible.
• Shrimp and snails: Do not assume the medication is safe for ornamental invertebrates. Use a separate treatment container when compatibility is uncertain.
• Marine aquariums: Some suppliers describe marine applications, but do not use this product in reef systems containing corals or other sensitive invertebrates.
• Aeration: Maintain adequate oxygen levels throughout treatment.
• Staining: Methylene blue is a strong dye that may stain aquarium silicone, equipment, clothing and surrounding surfaces.
• Overdosing: Never exceed the recommended dosage.
• Storage: Store below 30 degrees Celsius.
• Food fish: Not for use on fish intended for human consumption.

When treating sick fish, monitor ammonia and nitrite as well as the fish's symptoms. Medication does not replace appropriate biological filtration, regular water changes or accurate disease diagnosis.
