I'm willing to throw in my hat in the ring here and say that I would be willing to custom-build a acrylic multi-scrubber system as described. I am in the process of setting up an acrylics fabrication shop in my garage and I can add this to the list of projects.
I'm thinking that it would be beneficial to develop a planned scientific experiment. I'm thinking that starting an appropriately titled thread on this subject would be a good idea at this time.
