Randy, I have been contemplating what your are proposing to do. Personally I am in a situation where I can also start to dose a carbon source of choice. Noting the efforts of many other hobbyists (ie. Genetics), I would be glad to participate in any effort to extend the knowledge of carbon dosing. I have some additional funds that I am willing to supply either to you or to add to my own necessary equipment or supplies, if you so choose to run some kind of experiment.
