Hey Jack, no problem, like I said your comments help us to improve.
Now, regarding the chemicals you recommended and that are no longer available in the US… It is really funny because in my lab in Germany I have a huge container with Rewoquat and YES it is rather miraculous how it disassociates clay and silt. Strange that there is nothing similar in the US anymore. Maybe we can find a way to purchase a drum and bottle it in smaller portions. I will figure it out. Stay tuned …
all the best
