You should test you run off of fresh mix and used and give recipe if it's on point. You can use just a little in a cup and run through or your whole bucket...
Mine is like 4.3pH and 2,800ppm yikes!!! So don't ever listen to me going to ProMix now which is 6.5pH and 300ppm which is really like 100 because my water has 200.
I thought about sending in samples to get tested, along with samples from my lawn. I dont think that it cost as much as I first thought. $40 to sample my new compost! Sorry for the big diagram, I really thought that it was cool to see it.
This is Missouri, I am sure that there are other places just like this one!
