Discuss Rick Barnett's answer to: Chemical Allocation, who has equipment to track and dispense chemicals. Something like the Knight Edge system

That is why chemical companies keep tight control over this stuff.  Here is one outfit that will help you cover your behind in case some of your chemicals come up missing.
