Hi Johan - not a resident of HH so can't say where to purchase, but the first question would be that it depends on what you are using it for and what grade you are after. Judging by the fact that you are looking in pharmacies, it's not fertilizer, so obviously ''chemical grade''!! If looking at foodstuffs, wines, beers etc. and using as an antioxidant or preservative, then maybe look at Potassium Sulphite (K2SO3) instead - I suspect you would find this more readily available in pharmacies.

If you know any science teachers in a secondary school, they might be able to tell you.

In fact i'm looking for a fertilizer, i didn't find any anywhere so i started looking in pharmacies. I only know one shop who sell this but they are out of stock for a month and they are located in Chatuchak.

I don't need a high grade, just normal grade would be fine but without any other substance in it. I also know a manufacturer in China but they want to sell it by tons... and i only need 1kg at this moment.

It's for aquarium plants.

We buy fertilizer in Issan and although my partners family are the ones with the technical knowledge, I seem to remember that potassium sulphate is normally sold as a compound fertilizer with other things added and I haven't seen it in a pure form.
