I bought some standard calibrating CYA solution. Do I use the solution as is, or do I mix it with 50% tap water?
Use it as you would with pool water. Add it to the CYA testing bottle up to the label then add reagent up to the top of the label. Shake well and pour into the CYA viewing tube.

After a view you can pout from the tube back into the bottle and do another round of viewing to see how the dot looks as it approaches 50.
