Also FYI the powdered shock you have will (temporarily) cloud the water. Don't freak out. It will go away.
I noticed in your picture, it appears that you are filling the CYA test bottle all the way to the top which may skew the results a bit (not sure how much?) I attached a picture to show where the levels should be...pool water to bottom of label sticker and reagent to top of sticker...no higher.Yes 2nd cya test...it's a smidge cloudy, but I can fill the tube to 20 and still see that black dot. What is in my pool that is making it unable to see to the bottom?
Gothca. If you filled it like the instructions said, then you are good to go...just wanted to make sure you were getting accurate results. The CYA is somewhat of a PIA.Ill try it again. I was shaking it - it may have been a bubble up top
Yes, that is normal after it sits for a bit.My FC is now at 17.5 Bottle goes clear for about a minute then turns a lil pink again. Is that right?
