12voltdaddy,

Well if they are more into the feed they sure aren't doing a lot of weed control especially at that size. Sounds like it wouldn't be up to you to get rid of them but I was thinking... If one really wanted to get rid of grass carp, what about putting a Cutrine Plus granule or more mixed in water soaked pellets since Grass Carp are very sensitive to copper? Once you get them started on the feed, throw in the feed that has the copper. Just a thought. Never tried it. I don't know how much it would take to be lethal, but if they are like typical carp you ant to be careful they can't taste the granule.

Bill Cody taught me a way to hydrate fish food that causes it to get doughy so you can make dough balls out of it (not for poisoning fish though).

Here's how he does it for Aquamax: To one quart of pellets add 7 ounces of water. Small batches -- 1/2 cup of pellets to 1 Tablespoon of water. Shake pellets and water for one full minute until all water is absorbed and no "gravy" remains. Pellets should be shaken once or three times with the next 10 to 30 minutes to keep individual pellets from sticking together.

Bill uses a soaking container with a lid to keep in moisture. He lets the pellets soak up water for 2 to 6 hours;long is beter as it produces a more pliable pellet. Sometimes if the pellets are too dry after soaking he sprays a mist og water on them for an hour before use.

You want the pellets to be pliable but not sticky. If you don't squeeze the air out of them they will float. If you do they will sink.

Please if you do this DO NOT LET IT SIT AROUND CHILDREN OR PETS

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
