Re: pH and ammonia, Who said ammonia anyway

This is Charles Harrison in St. Louis

	I would like to interject the relationship of ammonia in our fresh
water systems is less than trivial. Ammonia does not exist at measurable
amounts at pHs we consider safe for our fish.
	Free measurable ammonia does not occur is water with a pH below 10.
Do the calculations yourself. Just remember that the amount of cation
charges and anion charges must balance, and ammonia in not ionized, it is a
gas dissolved in water. This kind of talk sounds like some kind of Witch
Craft, John.
