Description
Aquasonic Fungonex
Aquasonic Fungonex is a targeted freshwater aquarium treatment designed to control fungal infections in fish. Fungal disease is commonly identified by white or grey thread-like growths on the skin or fins, which can progress into small cotton-wool–like tufts if left untreated.
Fungal infections often develop after injury, stress, poor water quality or secondary bacterial infection. Prompt treatment with Aquasonic Fungonex helps limit disease spread and supports recovery when combined with good aquarium management.
Targets common freshwater fungal infections
Fungal infections are one of the most common diseases in freshwater aquariums. They typically appear as pale thread-like growths that later thicken into cotton-wool–like patches on fins and body surfaces.
Aquasonic Fungonex is formulated to treat these infections effectively when used at the correct dosage.
Importance of early treatment
Without prompt intervention, fungal disease can spread rapidly and lead to significant fish losses. Early treatment improves recovery outcomes and helps prevent secondary infections.
Directions for use
- Do not use on fish intended for human consumption.
- Perform a 25% partial water change before treatment.
- Ensure the aquarium is well aerated throughout treatment.
- Remove activated carbon from filtration systems.
- Handle carefully, as this product contains a dye that may stain.
Dose rate
- Standard dose: 5 mL per 20 litres of aquarium water.
- Sensitive species (tetras, juveniles, scaleless fish): 5 mL per 40 litres.
- Repeat treatment after 3 days if required.
How to calculate aquarium volume
To calculate approximate tank capacity:
Length × Width × Water Level Height (cm)
Divide the result by 1,000 to obtain litres.
Preventing future fungal outbreaks
Maintaining stable water quality, avoiding overcrowding and reducing fish stress are essential for preventing fungal disease. Regular water changes and prompt treatment of injuries reduce infection risk.

I spotted cotton‑like fungus on my guppy’s fin and panicked; this Fungonex treatment knocked it out fast and he’s swimming happily again.

I like that it’s a gentle fungal treatment with clear dosing instructions—using it early prevents the fungus from spreading and my fish don’t seem stressed during treatment.
