RE: [AGA Member] RE: Potassium


Most chemicals, dry or liquid are often bound with other things to make them more stable. It's entirely possible, and likely, that different people have different quality of chemicals which carry more or less of the specific molecule you want. It all depends on the Grade of chemical you buy and where the seller got theirs. One seller may have agricultural grade chemicals, which are less pure, but are cheaper, while another may have hydroponic and/or laboratory grade chems which are more pure but cost more. That often explains the differences in color and grain size between one hobbyists chemicals and anothers.

Hope this helps,
