CYA test mixing bottle

It is 14 ml to the bottom of the label, and 14 more ml to the top of the label, so 28 ml total. However, any measure that is 50/50 will work -- for example, 10 ml of pool water and 10 ml of reagent will work. You just won't have enough solution to fill the test tube, so this may not work if you CYA is very low.
