How to use?


Test your water quality using NT Labs Test Kits.

Mix the appropriate dosage in a clean bucket of pond water, pour evenly over the surface of the pond and leave for 7 days. Switch off UV filtration until the colour has gone from the water. Aerate the pond well during treatment.

If you feel a repeat dose is necessary, check your diagnosis using the Diagnosis Tool; a different medication may be more suitable. Allow 7 days after medicating and perform a partial water change before re- treating or treating with a different medication.

Always treat when you have time to observe fish and take appropriate action in the unlikely event of a bad reaction.



Do not use at water temperatures above 30°C.

Do not use in hot, humid or thundery weather.

Do not mix medications.
