Thanks for the link John. I like the idea of a hybird method like Iwan Lasser's. I think each ulns product lines have some very good products. I have some thoughts on how to combine Zeo and Ultra products in to a very effective UNLS dosing system. John do have any more links to Lasser's? I want to read more about his setup.
Here is another link I found
