When to use? White spot is a protozoan parasite; the adults live on the fish and appear as tiny white spots. The adult has a complex life cycle which results in hundreds of free-swimming juveniles looking for a host fish to infest. Use when small white spots, like grains of salt, can be seen scattered on the body of the fish, if the fish are showing signs of irritation and rubbing on objects in the aquarium, fish have a grey, velvety film all over the body, or fish have white cotton wool-like growths on their body/mouth/ fins. How to use? Calculate the volume of your aquarium in litres (length x width x depth (in cm)/1000). Alternatively, use our Dosage Calculator to help you. Shake the bottle thoroughly before use. Mix required dose of treatment with 1 litre of aquarium water. Add slowly to aquarium. Warning: This product will colour the water green and will also stain skin and clothing. The colour in the aquarium could take a few days to fade after the course has finished. Water changes can be carried out after the colour has faded. Changing water between doses is not recommended, except in an emergency.
