The kit mentions you can take a test with either 10ml or 25ml of sample water which you then use in cAlculations as .2 or .5.

The pool was swampy but very clear now. 20k vinyl inground.

Cya was 50 which I am surprised about because the pool store test I had done on last Tuesday was 19. I found this test a bit arbitrary. I am not sure if I did it correctly. Do you stop when the dot is completely hidden or when it's fuzzy? Also how long should i wait when doing the ph test to take a reading?

Thanks
