So...I took a water sample to Leslie's today. Why you ask? I've run out of CYA reagent because when I first got the pool I was practicing my testing skills a lot. Now I only test it about once a month. But the last couple times I tested it, I noticed that my CYA kept going down to the point that I only had 10. I started with 50. It went down to 40 after 2-3 weeks, then down to 30 in another couple weeks, then was down to 20, and on the last test it was basically non existent. So about a week and half ago, I added a 4 lb. pack of CYA from Walmart via the sock method. It took about 4 days to get it all dissolved. I didn't have any more reagent, so I was curious about whether my add had worked. The 4 lbs. was intended to raise CYA by 30 taking me back up to 40 and according to the Leslie's test I am now back to 40. I have more reagent ordered. When my CYA started fading, I had a more noticeable chlorine odor in the water and the water felt more drying on my skin. Now it feels and smells back to normal. I know that CYA is not supposed to leave the water. I thought perhaps my testing was flawed. But I feel pretty confident with it. Anyway, that's what appeared to happen. I did back wash the sand filter 3 three times over the last two months. But not long enough to drain enough water to lower it that much. I can't explain it. Maybe it was just so old that it broke down. Or maybe I over chlorinated because I thought the CYA was higher than it was and that destroyed what was left of it.
Anyway...the other reason I went in there is because I have some light stains on my plaster and I wanted to know if I have any metal in the water. I tried putting a puck on the stains and they did not budge. I don't have any metal tests. According to Leslie's there is no metal in my water. The girl said the stains are probably from leaves and then directed me to the stain remover potions. I read the label, and the potion is for calcium scale and metal stains. LOL. Since she just told me I don't have any metal and my CH is 210...I just winked and left. She had another customer trying to buy a sand filter.
Overall, the test she ran seems accurate.
FC 4
pH 7.4
TA 90
CH 210
CYA 40
TDS 500
Copper/Iron 0
Phosphates 100
She actually told me the numbers were great and I didn't need a thing. Was just kinda funny about the stain remover.
