Got A New Cyanuric Acid Test Kit But No Instructions With It

[Gavin]

it just has a tube and some cya acid. looks like this:

There were no instructions? Strange. Well, the normal instructions are to mix half pool water with half of the CYA reagent -- they may have a bottle with two lines on it for you to use. You then cap and mix this well for 30 seconds. Then you pour into the viewing tube and I believe with the test you have you fill up the tube and then move the slider black dot up and down until it just disappears and then read the ppm by some mark on the up/down portion relative to the outer tube.

The Taylor test is different in that it doesn't have an up/down tube movement, but you can read those instructions here.

ah ha! Thanks Richard. ok I will try that. I was wondering why the tube had a movable slider.

I do see an "A" and "B" marks on the back of the tube.

There you go, you fill with sample water to be tested to the A mark, fill with reagent to the B mark, shake the piston for 30 seconds, wait 1 minute, and pull up the cylinder until the black dot disappears, read the CYA level at the water level.

Same as the Taylor cylinder in their Counterlab, a much easier test to perform with this cylinder than the other ones proposed by Taylor.

To get the result, you need to look from the top of the tube into the solution. Slowly bring the piston up to the surface until you can see the black dot. The reading is then viewed from the markings on the slide. The result is the corresponding number at the water line.
