I haven't but I could, assuming just put the water in the jar as before but dont add ALUM this time right?

I have been measuring visibility each morning at 6AM. It was 48+ the first 2 mornings. Then the 2" all day rain event happened as mentioned above. The visibility went down to 30" and then the next day was 36 and this morning it was back down to 30. The water is real green so I am assuming that a good bloom is going on. I plan on taking a water sample on tuesday morning for Bill to analysis what the water is like a week later.
