So far the only place I can find it is aquarium shops. It is used as a filtering medium. I usually don't buy stuff online unless I can't find it locally.

Do not use the (swimming pool) filter version of DE for lots of reasons, mostly it can be hazardous to you when applying it. You can find DE at garden and feed stores with feed stores likely being the cheaper of the two.

I had a problem with slugs. I tried using beer but it didn't work, until I gave it to the slugs.
