IS this the correct dosage for using p.p for a bath to 40 litres of water half a tee spoon of p.p. then run air for 30 mins then add fish for two mins with air running.

Alex,
I use 6.8 grms. per1000 gallons, so I work out the dose for a dip from there depending on how much water is in the bowl, I am very cautious when using this product it is so fraught with danger, you must NEVER leave the pond alone when this treatment is added, and always have your H. P. ready to neutralise the water if something goes wrong.
