Hi, again, Kevin...(sorry I called you Ken)
From your response, I got the impression you were lukewarm about bringing your Cl to 18pp. I'm gonna' keep tryin' to convince you of the importance
This is from an article written by folks at North Carolina State and the whole thing follows Ben's recomendations very, very closely.
[QUOTE]Breakpoint Chlorination is the process by which combined chlorine and some organics are "burned out" of the pool by addition of large amounts of chlorine. The reaction of chlorine with ammonia to form chloramines occurs in several stages with free chlorine consumed at each stage. If enough chlorine is added to the water the total chlorine residual will rise to a point that forces the reaction of chlorine with ammonia to go rapidly to completion. Compounds of nitrogen and chlorine are released from the water and the apparent residual chlorine decreases. The point at which the chlorine residual suddenly drops is called the breakpoint. When enough chlorine is added to pass the breakpoint, combined chlorine compounds disappear, eye irritation potential and chlorine odors disappear, and the chlorine remaining in the water is all in the free state.[/QUOTE]
12ppm will not do this for you...18ppm will...go get 'em!!
