Algae Control is an high definition (NO3 - 0.25ppm PO4 0.02ppm) analytical comparator test kit (NO3 & PO4 -100 tests each) - incl. professional colorimetric comparatorIncludes: 100 Nitrate tests, and 100 Phosphate tests

Safety: Caution: Keep out of reach of children
Use Instructions: Directions for Nitrate Pro Test Kit:1. Using the syringe provided, place exactly 16 ml of the water to be tested into both of the glass vials.2. Insert one of the vials (control vial) into the outer hole of the comparator.3. Add 5 drops of Nitrate Pro reagent A to the second vial (Reaction vial) Close the vial with the cap and shake for 15 seconds.4. Add a leveled measuring spoon of Nitrate Pro Reagent B, close the vial with the cap and shake vigorously for 60 seconds.5. Add a leveled measuring spoon of Nitrate Pro Reagent C, close the vial with the cap and shake vigorously for 15 seconds.6. Wait 9 minutes for the color in the reaction vial to stabilize at the end point.7. Remove the cap from the reaction vial and shake the vial gently to release tiny air bubbles and reagent particles that settled on the bottom. insert the vial into the center hole of the comparator.8. When the end point of the test reaction has been reached look into both vials from above and rotate the color disc until the closest color match possible is achieved between the vials. Note: Turbidity or severe coloration of the water sample (high organic load) may distort the colors.9. The nitrate level corresponding to the color selected is printed on the color disc as indicated by the pointer on the side of the comparator body. If necessary, estimate an intermediate value.10. The color in the reaction vial will remain stable for 5 minutes. Do not relate to the color in the reaction vial after this time.High Range: For levels of nitrate above 4ppm dilute 1ml of the water to be tested with 15ml of RO water.Directions for Phosphate Pro Test Kit:1. Using the syringe provided, place exactly 17 ml of the water to be tested into both of the glass vials.2. Insert one of the vials (control vial) into the outer hole of the comparator.3. Add 10 drops of Phosphate Pro Reagent A to the other vial (reaction vial), close the vial with the cap and shake for a few seconds.4. Add 4 drops of Phosphate Pro Reagent B using the pipette, close the vial with the cap and shake for a few seconds.5. Remove the cap from the reaction vial and insert the vial into the center hole of the comparator.6. Wait 15 minutes for the color in the reaction vial to stabilize.NOTE: If the water sample has cooled to below 20°C wait for 20 minutes.7. When the end point of the test reaction has been reached look into both vials from above and rotate the color disc until the closest color match possible is achieved between the vials. Note: Turbidity or severe coloration of the water sample may distort the colors.8. The phosphate level corresponding to the color selected is printed on the color disc as indicated by the pointer on the side of the comparator body. If necessary, estimate an intermediate value.9. The color in the reaction vial will remain stable for 5 minutes. Do not relate to the color in the reaction vial after this time., Storage Instructions: Store in a cool, dry, well ventilated environment and away from direct sunlight. Keep containers closed when not in use."
