Potassium Sulphate

[schnad]

Hi,
I bought some Potassium sulphate from aquaess. in dry form. Followed the instructions to dissolve it, but it just doesn't want to dissolve. I shook, I warmed the water slightly and nothing happens. What do I do wrong?
Thank you Sandra

Yes it can be difficult to dissolve. I dissolve 46g in 1 litre of very hot water. The more concentrated you try to make it the more difficult it is to dissolve. Try warming up the solution by placing it in a microwave.

My K2SO4 was the hardest of my ferts to dissolve. Just keep stirring!
