IMO vertex is top of the line in membrane. I can't remember the number off the top of my head but maybe someone else will but they have a STUPID high amount of slits in their membranes, and the more tiny slits the better!!!! Remember tiny bubbles create your lift your looking for to bring your water back up to the surface and re-introduce it to the air on the top of the pond. Vertex creates a very nice uplift with all them tiny bubbles. As far as bases go you can use a lot of things.

1. A weighted down milk crate is good plus it keeps your fusers up off the ground some.

2. A nice larger used tire works good.

3. I am using metal panel off of a side of a computer.

Lots of good ideas out here.
