Taylor R-0009 Total Alkalinity Reagent (Sulfuric Acid .12N) – 500mL

Keep your pool water balanced and protected with the genuine Taylor Technologies R-0009 Total Alkalinity Reagent. This is the final titration reagent used in professional water testing kits to accurately measure Total Alkalinity levels.

Maintaining the correct Total Alkalinity is essential for stable water chemistry. If alkalinity is too low, your pool can experience rapid pH fluctuations, leading to corrosion, surface damage, and ineffective sanitiser performance.

💧 Why Total Alkalinity Matters

Total Alkalinity acts as a buffer, helping to stabilise pH levels and prevent sudden changes. Keeping it in the correct range protects your pool equipment, improves water clarity, and ensures swimmer comfort.

Frequently Asked Questions – Taylor R-0009 Total Alkalinity Reagent

What is Taylor R-0009 used for?
Taylor R-0009 is the final titration reagent used to measure Total Alkalinity in pool and spa water. It’s added drop-by-drop during testing until the colour changes, giving you an accurate reading.

What does Total Alkalinity do in a pool?
Total Alkalinity acts as a buffer for pH, helping prevent rapid fluctuations. Keeping it balanced protects your pool surface, equipment, and ensures your sanitiser works effectively.

How do I use Taylor R-0009?
After adding the initial reagents in your test kit, add R-0009 one drop at a time while swirling the sample until the colour changes. Count the drops to determine your Total Alkalinity level (as per your test kit instructions).

What is the ideal Total Alkalinity level?
For most pools, the recommended range is 80–120 ppm, though this can vary slightly depending on your pool type and sanitiser system.

Is this a genuine Taylor product?
Yes — this is a genuine Taylor Technologies replacement reagent, ensuring accurate and reliable test results.

How long does the reagent last?
When stored correctly (cool, dark place with the lid tightly sealed), reagents typically last 1–2 years. For best accuracy, avoid using expired chemicals.

Can I use this with any test kit?
Taylor R-0009 is designed for use with Taylor test kits, but it may also be compatible with other kits that use the same Total Alkalinity testing method.

What happens if Total Alkalinity is too low?
Low alkalinity can cause pH to swing rapidly, leading to corrosion of equipment, etching of surfaces, and uncomfortable water for swimmers.

What happens if Total Alkalinity is too high?
High alkalinity can cause cloudy water, scaling, and difficulty adjusting pH levels, making your pool harder to manage.
