Salifert Boron profi test

The test uses two parallel water samples. One acts as a colour reference, while B-2 and B-3 reagents are added to the second sample. B-3 is added drop by drop until the treated sample matches the reference.

Each B-3 drop added during the standard procedure corresponds to 0.5 mg/l boron. A separate reduced-sample procedure allows concentrations above 20 mg/l to be measured, with each drop then corresponding to 1 mg/l.

Directions

1. Wait at least 24 hours after the most recent boron addition.
2. Confirm that the sample pH is between 7.9 and 8.5.
3. Place two empty test vials side by side on a white background.
4. Add 8 ml of aquarium water to the left-hand vial.
5. Add eight drops of B-1 and one drop of B-3.
6. Swirl gently for 20 seconds.
7. If the colour is yellow, the pH is too low and the test cannot be performed.
8. Transfer 4 ml of the coloured sample to the right-hand vial.
9. Keep the left-hand vial as the colour reference.
10. Add one level scoop of B-2 to the right-hand vial.
11. Swirl gently for 20 seconds.
12. Add B-3 to the right-hand vial one drop at a time.
13. Swirl for ten seconds after each drop.
14. Stop when the colour matches the left-hand reference.
15. Multiply the number of B-3 drops by 0.5 mg/l.
16. Close the B-3 bottle immediately after testing.
