Aquasonic Ichonex 250mL – White Spot & Velvet Treatment

Aquasonic Ichonex 250mL is an Australian-made freshwater aquarium medication designed to help treat white spot (Ich) and velvet disease in ornamental fish. Formulated with copper sulphate and malachite green, Ichonex helps control the external parasites responsible for these common aquarium diseases.

White spot can spread quickly through an aquarium, causing small white spots on fish, scratching against decorations, clamped fins and breathing difficulties. Early identification and appropriate treatment are important for protecting affected fish and preventing further spread.

The economical 250mL bottle is particularly useful for larger freshwater aquariums, multiple tanks and fishkeepers who need sufficient medication for a complete treatment course.

Why Choose Aquasonic Ichonex?

• Treats freshwater white spot: Helps control Ichthyophthirius multifiliis, the parasite responsible for white spot disease.
• Helps treat velvet disease: Also formulated for susceptible freshwater velvet infections.
• Targeted antiparasitic ingredients: Contains copper sulphate and malachite green.
• Three-day dosing schedule: Uses an initial treatment followed by reduced doses on days two and three.
• Suitable for larger aquariums: The 250mL bottle provides approximately 1,000 litres of complete three-day treatment coverage.
• Australian-made: Manufactured by Aquasonic for ornamental aquarium fish.

What Is White Spot Disease?

White spot, also called Ich, is a parasitic infection caused by Ichthyophthirius multifiliis. The parasite affects the skin and gills of freshwater fish and can spread rapidly between fish sharing the same aquarium.

Common symptoms include:

• Small white spots resembling grains of salt on the fins, body or gill area.
• Fish rubbing or scratching against gravel and aquarium decorations.
• Clamped fins and reduced swimming activity.
• Loss of appetite or unusual hiding behaviour.
• Rapid breathing or signs of respiratory distress.

White spots are not always caused by Ich. Some bacterial, fungal and other parasitic infections can produce similar symptoms, so accurate identification is important before starting medication.

How Aquasonic Ichonex Works

The white spot parasite has several stages in its life cycle. While some stages develop within the fish's tissues, other stages are exposed in aquarium water and are more susceptible to treatment.

Aquasonic Ichonex combines copper sulphate and malachite green to help control susceptible stages of the parasite. Following the recommended treatment schedule is important because a single dose may not reach every parasite.

Treatment effectiveness depends on correct dosing, aquarium water conditions and the susceptibility of the organisms being treated.

How to Use Aquasonic Ichonex 250mL

Calculate your aquarium's actual water volume before dosing and follow the instructions on the product packaging.

1. Confirm that the fish are showing symptoms consistent with white spot or velvet disease.
2. Remove activated carbon from your filtration system while maintaining biological filtration.
3. Provide strong aeration and good water circulation during treatment.
4. Check that all fish and other inhabitants can tolerate copper-based medication.
5. Apply the appropriate dosage according to the three-day treatment schedule.
6. Monitor fish behaviour and water quality throughout the treatment.

Three-Day Treatment Dosage

• Day 1: Add 5mL per 40 litres of aquarium water.
• Day 2: Add 2.5mL per 40 litres of aquarium water.
• Day 3: Add 2.5mL per 40 litres of aquarium water.

For best results, Aquasonic recommends dividing each day's dosage into two equal applications, administered morning and evening.

250mL bottle coverage: A complete three-day treatment requires 10mL per 40 litres. One 250mL bottle therefore provides enough medication for approximately 1,000 litres across a complete standard treatment course.

Important: Do not overdose. Copper becomes more toxic under acidic water conditions. Aquasonic recommends maintaining pH above 7.5 where appropriate and monitoring copper concentrations with a suitable test kit. Never make sudden pH changes that may stress your fish.

Important Treatment Precautions

• Freshwater use only: This product is not intended for treating marine white spot.
• Shrimp and snails: Copper can be highly toxic to freshwater invertebrates. Do not use Ichonex in aquariums containing shrimp, snails or other sensitive invertebrates.
• Catfish and loaches: Some species are particularly sensitive to copper medications. Check species compatibility before treatment.
• Juvenile fish: Young fish may be more sensitive to medication. Seek species-specific advice and follow any reduced-dose instructions supplied by the manufacturer.
• Live plants: Copper may adversely affect sensitive aquarium plants.
• Activated carbon: Remove carbon during treatment because it may absorb medication.
• Aeration: Maintain adequate dissolved oxygen throughout the treatment period.
• Water chemistry: Monitor pH, ammonia, nitrite and copper levels during treatment.
• Temperature: Avoid sudden temperature changes or raising the temperature beyond the tolerance of the fish.
• Storage: Store below 30 degrees Celsius with the lid securely closed.

If your aquarium contains copper-sensitive fish, shrimp or snails, a separate hospital aquarium may be a more appropriate treatment option. Seek aquatic veterinary advice if symptoms are severe or the diagnosis is uncertain.

Frequently Asked Questions

What does Aquasonic Ichonex treat?

Aquasonic Ichonex is formulated to help treat freshwater white spot disease caused by Ichthyophthirius multifiliis and certain freshwater velvet infections. Both conditions are caused by external parasites.

How much Ichonex should I add to my aquarium?

Add 5mL per 40 litres of aquarium water on the first day, followed by 2.5mL per 40 litres on days two and three. Always follow the product label and calculate the actual volume of aquarium water.

How much water does Ichonex 250mL treat?

The 250mL bottle provides enough medication to treat approximately 1,000 litres of aquarium water across one complete standard three-day treatment course.

Is Aquasonic Ichonex safe for shrimp and snails?

No. Ichonex contains copper sulphate, which can be highly toxic to shrimp, snails and other freshwater invertebrates. A separate hospital aquarium should be considered when treating fish from an invertebrate aquarium.

Can I use Ichonex with catfish or loaches?

Some catfish and loaches are sensitive to copper-based medications. Seek species-specific advice and follow manufacturer precautions before treating these fish.

Should I remove activated carbon during treatment?

Yes. Activated carbon can absorb aquarium medication and reduce its effectiveness. Remove carbon while continuing biological filtration and aeration.

Does Ichonex treat fungal infections?

Ichonex is primarily intended for freshwater white spot and velvet disease. Fungal infections have different causes and may require an appropriate fungal treatment, such as Aquasonic Fungonex, following correct diagnosis.

Can Aquasonic Ichonex be used in marine aquariums?

No. This product is intended for freshwater aquarium fish. Marine white spot is caused by a different parasite and requires appropriate saltwater treatment.
