So true about the water picking up the soil parameters. After the big rain (which maybe added 1.5-2 acre-feet) I rechecked the pH with my cheap aquarium strip. Although I tested near the water's edge where the water was in close contact with the soil, the pH was 6.2 now, as opposed to the sample that I sent to LSU, which was 7.07. I am thinking about adding some more hydrated lime slurry to bring up the pH a bit until we get the next big rain. After my pH is OK and stable, then I will attempt to add an alum/lime mix to get rid of the cloudiness without dropping the pH. Found a link for the concoction here
