Hello Guys, Im a newbie on the site. Ive been looking for the best way to do the bucket test, but just see bits and pieces. What I have is about a 1 Acre pond, (deepest part is 12-15 FT.)that my father dug 24 years ago. There was a lot of clay, and the pond never cleared. At its best maybe 1 ft. of visibility. I just purchased the property, and just heard of the Alum treatment. Im looking for the formula or amounts of recommended Alum to add. Any help would be appreciated.

Welcome to the forum.

You have to counter the alum with hydrated lime too. For every pound of alum, use 1/2 pound of hydrated lime. (in the pond)

The bucket test will allow you to roughly figure out how much aluminum sulfate to use.

1 acre, 12-15 feet at the deepest could require 2200 pounds of alum and 1100 pounds of hydrated lime.

Look in the Muddy water section. For the bucket test, basically you take a given volume of water and keep adding alum to it until it flocculates and precipitates the clay out of solution. You then calculate how much alum you used per gallon of water and translate that to how many gallons of water are in your pond. That will tell you how much alum to use, and you have to buffer that with 50% hydrated lime to keep the pH from crashing and killing the fish.

3/4 to 1 1/4 ac pond LMB, SMB, PS, BG, RES, CC, YP, Bardello BG, (RBT & Blue Tilapia - seasonal).

What is a good mixing ratio of spraying/ treating pond, that is the mixture of Alum/water dilution?
