Why Test Potassium?
Routine potassium testing is crucial in coral reef aquariums supplemented with potassium. This element has an essential role in the transportation of coral nutrients within the soft tissues including the nutrients provided by the zooxanthallae. Potassium also has a significant effect on the alkalinity inside the coral soft tissue and plays a role in the formation of aragonite in the coral skeleton. Potassium is related to the red chromo-proteins (peridinin and neo-peridinin).
Proper potassium supplementation encourages enhanced coral coloration for a stunning and vibrantly-colored reef aquarium. However, overdose of potassium can encourage the breakout of nuisance algae. Therefore, correct dosage of potassium supplements and routine potassium testing is crucial to the health and success of any reef aquarium.

Directions for Potassium Pro Test Kit
- Prepare the Filtration Kit as follows:
- Lay a clean dry Filter Paper above the Funnel
- Place the Top Cylinder on the Filter Paper and push down, trapping the Filter Paper between the Cylinder and the Funnel
- Place the assembled Filter onto the Filter Cup
- Using the large syringe provided, place exactly 2 ml of the water to be tested into one of the glass vials.
- Add exactly 3ml of RO or distilled water to the 2 ml water sample.
- Add 4 drops of Potassium Pro Reagent A. Close the vial with the cap and shake for 15 seconds.
- Add 11 drops of Potassium Pro Reagent B. Close the vial with the cap and shake for 15 seconds.
- Wait for 10 minutes (use a stopwatch) and then pour all of liquid from the glass vial into the top of the filter.
- Wait (approx 7 minutes) until at least 3ml of clear liquid has collected in the Filter Cup (above the line), remove the filter and dispose of any remaining liquid. Using the 5ml syringe, take exactly 3ml of the filtered clear liquid from the filter cup and put it into the 2nd glass vial.
- Ensure that the dispensing tip is on the 1 ml titration syringe and fill with 0.5 ml of Potassium Pro Titrant D. Note for filling the 1ml titration syringe: Raise the plunger of the syringe until the bottom ring of the plunger is at the 1.0 ml mark. The surface of the liquid will be approximately 0.1 - 0.15 ml below the plunger. Do not try to remove the air trapped between the liquid and the plunger. This small volume of air corresponds to the liquid held inside the plastic tip.
- Insert the syringe into the center of the Titrator so that the volumetric scale on the side of the syringe is visible. The graduations of the volumetric scale are 0.01 ml, equivalent to 3 ppm of potassium.
- Add 2 drops of Potassium Pro Reagent C and mix gently. The test sample will now have the titration start color as shown on the instruction card.
- Screw the glass vial onto the bottom of the Titrator.
- Add one drop at a time of Potassium Pro Titrant D by pressing the plunger of the syringe and gently swirling after each drop, until the end color is achieved. Pay careful attention to the color of the test sample from the addition of the first drop. Note: The amount of titrant used is inversely proportional to the level of potassium in the aquarium water sample. If you reach the end color on adding the first drop, the potassium level is 467 ppm or above.
- Note the amount of titrant used (according to the initial and final position of the plunger, not the liquid surface) and use the table to calculate the level of potassium in the water sample.
- Dispose of any unused quantity of titrant. Rinse all syringes, glass vials and filter kit with RO or distilled water before storing. Filter Papers are for single use only and cannot be reused.
Important notes for using the Potassium Pro Test Kit
- Before carrying out any water testing, always check the salinity and make adjustments as necessary. If you have made adjustments to the water, wait 10 minutes for the water parameters to stabilize (e.g. 1ppt increase in salinity due to evaporation of fresh water will result in an approximate increase of 13ppm Ca).
- Before testing, clean the glass vial and the large syringe by rinsing it with the water to be tested.
- After testing, rinse all syringes and vials with RO or distilled water before storing. If vials are left unwashed, a residue can form that will affect the results of future tests. Use a slightly acidic solution such as vinegar to remove the residue.
- Close all reagents tightly immediately after use.
- The test reagents are stable up to the date stated on the pack when stored closed between 15 - 25°C (59 - 77°F).
- Store the reagents and color card in the plastic box to prevent damage from prolonged exposure to light.
