Interesting bit of math that suddenly brings into question the accuracy of ammonia tests... specifically what ever missleman is using.
Here's some numbers:
missileman used 1/2 teaspoon in a 75 gallon tank to get 3ppm.
Here's the math I get (tell me where you think I have my facts wrong).
1 teaspoon = 1/6 U.S. fl. oz (by U.S. law: 1 teaspoon = 5mL, but this old measure is close enough).
1 gallon = 128 oz.
Given a 10% solution of ammonia, that means the tank was dosed with 1/120 of an oz of ammonia (1/12 of an oz of a 10% solution).
Given a 75 gallon tank, that is 9,600 oz.
That makes for 1 oz of ammonia for every 1,152,000 oz of water. That's less than 1 ppm.
Even accounting for the fact that substrait, decorations, and even air (the tank was presumably NOT filled to over flowing) That changes the calculations by less than 20%.
The math just isn't there for that little bit of ammonia to equal 3ppm.
Where are the other 2ppm coming from (or perhaps stated differently, why is the test seeming off by a factor of three)?
1.1ppm of ammonia in the tank. But missileman measured 3ppm. Why the difference?
Of course some of the difference is that his tank did not have 75 gallons of water. Presumably 75 gallons is what the tank holds if filled to over flowing, and presumably he has some substrait and decorations in the tank. So as a GUESS, missileman only had 60 gallons of water in the tank.
