I would suggest removing the CYA now and see were it settles. I imagine you had 20+ ppm CYA in the water.
Not sure what you mean by removing the CYA, it was completely gone from the socks within a few hours of when I put it in last night.I would suggest removing the CYA now and see were it settles. I imagine you had 20+ ppm CYA in the water.

I read your post, and I am confused. If I run the test again, and shoot for the dot not completely dissappearing like in your picture, that means I will be adding less test solution, which would make the reading even higher. I am good with the 50 it is now, but if I follow your method, it would for sure be at least 10 higher. I ran out of reagent, and I wont have new bottle until Thursday, but can test again then, and let you know.Realistically, it would show a lower amount not being fully dissolved. Read my comment above I added some after you replied. I would be interested to know what your test shows if you make your CYA look exactly like my picture.
Sorry - I assumed not all was dissolved yet.Not sure what you mean by removing the CYA, it was completely gone from the socks within a few hours of when I put it in last night.
So you got me thinking about pool size, so I went out and measured everything, and plan to use my geometry skills to calculate each section, but I also ran my dimensions into several online calculators that ask for length, width, deepest depth and shallowest depth, and it came out at 26,730.It's also possible your pool is smaller then you thought. Especially if you are going by what the builder told you.![]()

My water temp is pretty cold right now, it is about 55 degrees. The issue with calculating size, is that the sides for about 75% of the length are straight for 3', then they slope. So when you get to the deep end, there is a 6' square section in the middle that is 8', but beyond that on all sides, the depth gradully decreases from 8' to 3'. Hard to explain without showing a picture, but it is a common design for vinyl IG pools. When I pulled the water for the test, I pulled it from the same corner that I had the sock hanging, but that sock had been empty for at least 15 hours, so I doubt it was still concentrated there. I am going to order a standard solution of CYA to better calibrate my test, then go from there. For now, I am going to base my target shock FC on a CYA of 50.With a rectangle pool it's fairly easy to accurately calculate the size. Not sure why else you would be measuring too much unless you happened to hit a pocket of water where the CYA was unusually concentrated. Wait a couple days and try again. What is your water temp?
Where did you buy the reference CYA solution? I have looked all over Amazon, and the Taylor site, and cannot find anything except pH calibration solution.I bought the 50 ppm reference CYA fluid and tested it.

Yes, it is the top left (standard hopper) design.Something like one of these?

Thanks, I just ordered one. Of course after reading other TFP posts about varying results using the standard solution, I am not sure what it will tell me though. We shall see what readings I get and go from there.
It actually shows how many are not accurately interpreting their CYA test resultsThanks, I just ordered one. Of course after reading other TFP posts about varying results using the standard solution, I am not sure what it will tell me though. We shall see what readings I get and go from there.
