I was just curious. I have a cloudy pool right now which has read 0 for CYA. My pool is 10K gallons and usually 2 gallons of liquid CYA does the trick to get the levels back up. What i'm confused about is that a week ago i put in 2 gallons and the reading remained 0. I figured it was a fluke and did it once more this morning and am still reading 0. Is this possible ?
I usually do CYA first before trying to bother with adust the chlorine amounts, ph ,etc. which is obviously what i'm now going to go and do, but I guess, i had thought that CYA was the first thing to do so my chlorine would be protected from the sun.
1. Is it possible to put too much cya in ?
2. Our sand filter probably needs to be replaced soon (hasn't been done a few years) , could that be a factor ?
I will get my readings posted here as I know that's usually the first information you guys request but i thought i'd put up those two questions above in case they might be factors and see what you thought. Thanks,
