Usually put out by spreader truck. Just shovel it to deeper water. It is better if it is spread over the entire pond bottom but will do ok if spread around the near shore water bottom ( about 20% of the bottom but in different locations).

Greg the effectiveness and absorption rate depends on lots of things as you noted. When we put in 1 ton per acre (when alkalinity gets to about 20) we see a quick upturn ( a week) of about 3-4 ppm as the initial gray cloud of limed water spreads out. That is the part that dissolves on contact with the water and turns the water cloudy gray. In about a mth to 6 weeks we see a gradual rise start which lasts for about 8-10 mths . At that point the alkalinity stabilizes for about 6 mths and then starts down at a gradual rate for about 8-10 mths. At that point it is back to about 20 ppm. If you plot that you get close to a bell curve.
