CYA Test

Hi, Ted/John

We're sort of hijacking this thread but, yeah, I'm in the dark as to the wide variance as well. My last CYA addition of 11 lbs (35ppm) tested complete after 48 hours.......possibly sooner. I wonder if the age of the product has any effect.

Ted, what are you doing putting that stuff in the pool where the customers can see it? HIDE it in the filter!!! If they backwash, you get to sell them more!!

Dave/John:
Thanks for the input, I agree. - Most of the pools we do are 'sport' pools (deep end >6') and the cya is usually all gone in 5 days or less. When I have to add salt to make up for winterizing loss I add 1 lb cya: 100 lb salt to get to ~30ppm cya ( if the pool is clean and won't need to be backwashed, I add it to the skimmer - if not I leave the cya for the homeowner to add once the pool is cleaned up). I think the sock in the skimmer is a great idea( though I'll use knee-high stockings - used to use them all the time for plaster stains, putting a handful of cal hypo and a stone in one to bleach out the stain.
If they backwash, you get to sell them more!!

Dave, I'm shocked! , you should know me well enough by now to know that I don't sell anything - (I know you were just kidding but I can't stand the fact that the company I work for uses the automated chem selling tester which usually ends up causing more problems than it solves and I can't get them to stop or tone it down because they make money off of it )

(typical Waste post - I try to use some of the cooler functions available here and end up with the text saying what I wanted, but improperly formatted!! - sorry all!
