King British Original WS3 White Spot Control is a full strength White Spot terminator, which treats fish with external parasites including White Spot (Ich), Costia & Trichodina. A parasite is an organism that attaches itself to a host and absorbs nutrients from the body fluids for its own growth and development, with no beneficial (and often detrimental) effects on the host. White spot is one of the most common parasitic problems affecting fish. It is not visible to the naked eye in its swimming state or on the host fish for the first two days. It grows rapidly and appears as small pinhead-sized white spots on the body & fins.
After 5–7 days the spots break up into smaller parasites and rapidly reinfect the fish. If left untreated, fish quickly become sluggish, their fins will disintegrate and the fish may die. Care should be taken when diagnosing White Spot, especially in Clown Loach fish, which can show spots resulting from poor water quality. This may not be White Spot. King British Original WS3 White Spot Control can be used in Tropical & Coldwater aquariums.
King British Guidance: use Original Formula WS3: if fish appear to have small pinhead-sized white spots on their body & fins, when fish flick or rub themselves against objects, when fish have rapid gill movement, when new fish are introduced to the aquarium, or use as a preventative treatment against white spot and parasites.
