Various companies are making drug testing pee cups that are evidently accurate enough that non-experts can use them to not-hire or fire.
Are you aware of any company making a cup that anybody (even the janitor) can fill from a saltwater reef tank and report the basics such as nitrate, ammonia, conductivity, pH, and carbohydrate?
