Whats Included?

Instructions

20ml K-1 Liquid Reagent
10ml K-2 Liquid Reagent
10ml K-3 Liquid Reagent
2x 1mL Syringe
2x Testing Vials

 

Instructions:

Importaint Note – Before commencing with each test it is very important to clean the nozzle (including the tip) of the K-3 dropper bottle with a paper tissue. Even if the nozzle looks clean and dry. Do this by applying a slight pressure on the tissue while cleaning

Do NOT put the cap back on the K-3 bottle until the test has been completed.

 

1. With the unlabeled syringe add 1mL of aquarium water to the test vial. There will be a small air bubble (approx. 0.05 mL) in the syringe do NOT attempt to remove the air bubble.

 

2. Add 0.5 mL of K-1 using the red labeled syringe in the test vial. There will be a small air bubble (approx. 0.05 mL) in the syringe do NOT attempt to remove the air bubble. Swirl the test vial gently for at least 20 seconds.

 

3. Add to the test vial 3 drops of K-2 while holding the dropper bottle in a vertical position. There is no need to swirl the test vial after this step.

 

4. Add to the test vial K-3 one drop at a time, while holding the dropper bottle in a vertical position. Swirl the test vial for 2 seconds in between each drop of reagent. Continue adding K-3 while counting drops and swirling between each until the color changes from a white or yellowish color to a baby blue / light blue color. The change is very dramatic.

 

5. After color change is complete compare number of drops to ppm potassium chart below.

 

An extra testing vial is included with the kit for convenience and only a one vial is needed for a single test. That lets you to use one vial while the other is being cleaned. With potassium test kits it is important to keep reagent tips, syringes and testing vials clean for reliable readings.

Holding the reagent bottle directly vertical will allow for even and consistent drops making readings reliable and repeatable.

Description

Potassium concentration in natural seawater is approximately 400 ppm. Many aquarists have reported that a low potassium value reduces colors in corals. This can be corrected by increasing the potassium value to the normal natural concentration. Now you can accurately measure this value with the new Salifert Potassium Reef Test kits.
