Yep I'm shmart. Whatever that is. \:D

Bruce,

I got Alum pretty cheap from a Chemical supply in one of the nearest big cities. If I remember right it was only about $11.00 a 50 lb. bag but I could be wrong. (Somewhere in that price range) Sure was much, much, less than what the aquaculture supply catalogs were selling it for. And of course no shipping as the wife picked it up for me.

I just did an Internet search to find the chemical company. It's used a lot by sewage treatment plants so you can always ask them where to get it if you Internet search does not pan out.

I made a slurry with it in large garbage cans spaced evenly around the .69 acre pond. Then using a gallon plastic pitcher cast it over the surface. I filled the garbage containers with sump pump, I couldn't see why you couldn't spread it with a sump pump also. Didn't bother the fish and it never dropped my Ph even though I added quite a bit.

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