1/4 acre pond (more or less), 12 foot deep, sand/clay soil.

I tested my water today and my alkalinity is very low, probably around 20ppm using a pool test strip. The ph on the strip indicated between 7.5-7.8, but when I used my wide range ph test kit it was closer to 9 (thinking that's probably more accurate) I'm going after 500 lbs of garden lime tomorrow and get it in the pond to try to bump the Alk. How long should I wait before checking the Alk level again....and if it comes up sufficiently, will this neutralize the ph automatically or will I have to do something else?

Visibility is approximately 20 inches, but the water has a good olive green color (finally) and I do have some sparse algae on the surface.
