This pond fish treatment tackles white spot, anchor worm, fish lice, ulcers, and bacterial skin infections in garden ponds. Safe for use with koi, goldfish, and most pond fish when used as directed. Treats up to 10,000 litres per 500ml bottle. Fast-acting formula for rapid recovery of affected fish.

Act Quickly When Your Pond Fish Show Signs of Illness

Fish disease can escalate rapidly in pond environments, where infection spreads through the water to every fish within days. Early identification and prompt treatment are essential. Common signs to watch for include white spots on fins and body, ulcers or open wounds, fish rubbing against surfaces (flashing), lethargy, loss of appetite, and reddening around the gills or fins.

What It Treats

• ✅ White spot (Ichthyophthirius multifiliis) — tiny white cysts on skin and fins
• ✅ Skin and gill parasites — including trichodina, costia, and chilodonella
• ✅ Anchor worm (Lernaea) and fish lice (Argulus)
• ✅ Ulcers and open wounds — bacterial skin infections (Aeromonas)
• ✅ Fin rot and tail rot
• ✅ Fungal infections secondary to wounds and parasites

Dosage and Application

Important Application Notes

Before treating, always calculate your pond volume accurately (length × width × average depth in metres × 1,000 = litres). Measure the dose carefully and dilute in a bucket of pond water before distributing evenly across the pond surface. Switch off your UV clarifier during treatment — UV light rapidly degrades the active ingredients. Ensure good aeration throughout the treatment period.

Frequently Asked Questions

Is it safe for koi and goldfish?

Yes, when used at the correct dosage. Always calculate your exact pond volume and measure carefully. Fish should show improved behaviour within 3–5 days of correct treatment.

Should I switch off my filter during treatment?

Keep your biological filter running — the bacteria it houses are beneficial. However, switch off any UV clarifier, as UV light breaks down the active ingredients.

How quickly will I see results?

Improvement in fish behaviour is typically seen within 48–72 hours. White spot cysts begin to drop off within 5–7 days. A second treatment after 7 days may be required for heavy infestations.

Is it safe for plants and wildlife?

Designed for fish ponds. We recommend removing sensitive aquatic plants before treatment and avoiding use in ponds containing amphibians or invertebrates.

How do I prevent reinfection?

Quarantine all new fish for a minimum of 3 weeks before introducing to the main pond. Maintain good water quality through regular partial water changes and adequate filtration.
