What does ammonia do to a pool?

[waterbear]

I came across an 'old time pool guy' recipe for reaching breakpoint. Not recommending you try this it and Richard (chem geek) or Ben might want to comment on this.
(Ben, feel free to move this to china shop if it really should be there!)
For each 20000 gallons add 1 gallon of anhydrous ammonia and 8 gallons of 12.5% liquid chloine (this will raise the FC 50 ppm!) with pump off for 24 hours. Turn pump back on and let chorine levels drop to normal.

Seems like overkill to me!

I'm moving this to a new thread in The China Shop called Breakpoint Chlorination. Follow me there...
