You'll probably need about 600-800 lbs of hydrated lime for this project. It is a messy job, but cheap and very effective. We pour our lime into a 5 gallon bucket and walk around the pond bottom spreading as we walk. HL is caustic, will burn your eyes, and will dry out your skin. Use the wind to your advantage. Don't apply without a breeze. With a breeze walk into the wind. When you've used enough HL you will see the mud start to floc and settle and fish will start to die. The next day you should see all dead fish clear to the bottom, crystal clear water. Around here HL costs about $7 per 50 lb bag.

Another option is to use a small boat with trolling motor, but 8 inches of water isn't much and you might find yourself in a bind.

HL is our product of choice for killing fish in a drained pond.

It's ALL about the fish!
