KH/ALK profi test Salifert test

Profi test Kh/Alk allows you to monitor the carbonates present in your marine aquarium. This product, consisting of two solutions, enables you to perform 100 to 200 tests. Our opinion: Salifert tests are reliable and very affordable.

KH / Alk French WARNING Keep out of reach of children! Do not swallow!

The KH-Ind reagent contains a dye. Avoid spilling the dye on fabric or other materials, as they could be stained.

INSTRUCTIONS:

1] Pour 4 ml of water into the test vial using the 5 ml syringe. For lower resolution and to allow for more tests per kit, only pour 2 ml instead of 4.

2] Shake the KH-Ind dropper bottle several times and add 4 drops into the test vial. (2 drops for a low-resolution test).

3] Firmly place the plastic cone on the 1 ml syringe, and fill it with the KH reagent until the lower part of the black piston is at the 1.00 ml mark. Ensure, during this operation, that the cone remains submerged in the reagent to avoid drawing air bubbles instead of liquid. An air layer between the piston and the liquid is normal. This is the air that was present between the tip of the cone and the piston. It will not affect the result.

4] Begin adding the KH reagent into the test vial with the 1 ml syringe, until the color changes from blue/green to an orange-red or pink color (regardless of the initial color observed). Stir for a second or two after each drop added.

5] Holding the syringe with the cone upwards, read the position of the upper part of the piston.

Each graduation corresponds to 0.01 ml. The KH or alkalinity can be obtained using the table below.

If you chose to perform a low-resolution test, multiply the calculated result by 2. Natural seawater has a KH of 7-8 dKH. The KH and alkalinity can be safely increased with Salifert's KH + pH Buffer.
