I purchase from chemical stores 500gr powder form. the info I work from a pond forum. I mix a stock solution of 7.5 grams to 100ml. distilled water in a dripper bottle. treatment 0.5 drops of the solution per liter of aquarium to achieve a 2ppm treatment level. 0.25 drop per liter equals 1ppm. you can go up to 5ppm for a hospital treatment, but be careful. there are several concentrations on available from pond keepers on the web. I find 2 ppm concentration doesnt kill snails (which I keep in my breeding and grow out tanks), but it brings pathogens down in established tanks and ponds. I have several grow out troughs with gravel bottoms that I do not sterilize, I add the PP periodically to keep things in check between yield cycles. give the pond a soak with PP for a few hours until the color turns from pinkish purple to brownish tea, the use hydrogen peroxide to deactivate it (as shown in the vid above). then 50% water change. @rjv23Thank you very much this is helpful. I do need to get a smaller scale, my digital scale doesn't measure in MG I mostly use it for baking/cooking in larger volumes, however I know 4Mg is about 1/16 of a teaspoon I believe, or I need a dripper bottle and premix it like you mentioned below. I'll go find a dripper bottle today or tomorrow maybe, then I can try using this dripper method as I can measure out grams easier then MG and just add 1 drop in his 2L container for his bath.
