Re: [APD] Re: Ammo Lock and Ammonia Tests
For those interested in the ratio of ammonia to ammonium,
or vice versa, as it relates to pH, the following info
comes from _The Aquatic Gardener_, which quoted the
material from Roger Miller, who took the info from the
source mention below:
Lifting a few numbers from Spotte (1970 ed., p 104), the
percentage [of ammonia & ammonium that occurs] as ammonia
at 20 degrees C is:
pH %ammonia
7.0 0.5
7.5 1.5
8.0 4.7
8.5 13.7
9.0 35.8
9.5 62.1
Good luck, good fun,
Scott H.
