Did the Alum treatment thing today & think it went ok. It did lower the pH from 7 to 6.5 in spite of 500lbs lime. I put out 1000lbs of Alum on about 2 1/2 surface acres. My set up was to use pontoon boat with 80 gal water trough to mix the Alum in
I tied a float to the suction side, threw it overboard, then filled the trough with 50 gal water
Then added 50lb Alum & mixed it with an oar.
Then put the suction side in the trough & sprayed the slurry over the pond surface
The water was starting to clear after about 5 hrs(went from 3" to 9" visibility)of spraying, so will interested to see how it looks this weekend..du
