Pond Boss Forums GENERAL QUESTIONS Pond Boss What to do with 600 extra pounds of Hydrated Lime

So I bought a bunch of this stuff a few years ago in bulk (clearly) and now I have extra. I could just take it to the landfill, but my county charges by the pound. I could just suck up the $20 cost and do that, but I feel like it shouldn't be hard to give away.

I've had an add on craigslist for a month now with no inquiries.

Thoughts?
