Hey Bob Thanks for the site. Wow, I guess I've been paying through the nose for bags. They have every size I could imagine. I do like the 2.0 mil bags only because of the fact that they are alittle more sturdy and less likely to get a hole poked in them or even deflate as easily. Those larger bags that are the 2.5 mil are for large cichlids. That is all I use them for. I would think that a 1.0mil bag would be too thin. Don't know how well they hold up.
