These instructions are for use with test kits based on Taylor chemistry, such as the TF-100, the TF-50, the Taylor K-2006, the Leslie's Chlorine FAS-DPD Service Test Kit, and also a few other test kits.
The Taylor K-2006, the TF-100, and the TF-50 have the exact same reagents, except the pH reagent is different and not interchangeable and the TF-50 does not come with a pH test.

When doing the CYA test, it is important to let the water sample warm up to room temperature. The Chlorine and PH tests should be done right away, regardless of the water temperature. The TA test is not affected by the water temperature. The CH test should be swirled a little longer in cold water but otherwise not affected by the water sample temperature.

When measuring the volume of your water sample in the cylinder, the top of the water sample will be curved. The curve is called a meniscus. The bottom of the meniscus should be level with the mark on the cylinder. It becomes more critical to get the volume correct when measuring the volume of smaller water samples because 1 mL off either way can add another 10% to the accuracy of the test.

Rinse your equipment before and after each test.

Collect your pool water samples about a foot under the surface.

Hold the dropper bottles vertically and squeeze gently, so that drops come out slowly and seem to hang on the tip of the dropper bottle for a moment before falling. It is not the size of the opening of the tip, it is the surface tension of the drops coming out that determine the size of the drop. The tip is designed to hold the fluid on the end until gravity overcomes the surface tension and the drop falls off the tip.

Keep your chemistry clean and dry and out of the sun, heat, and humidity, storing in a temperature range of 36-85F is preferred. All reagents have a shelf life and how you store it matters the most. Taylor recommends replacing reagents that are more than a year old, or at the beginning of a new testing season.
