Checking the correct concentration of reagent
For correct operation and measurement of KH by the KH keeper Plus it is essential that the reagent is fed into the vessel in the correct quantity and concentration. The correctness of the reagent concentration can be checked using the Reef Factory Smart KH Smart test kit or the Salifert KH/Alk drop test. When checking the correct concentration of the reagent, 2 KH drop tests of the aquarium water should be performed. Perform the first test fully as instructed and note the remaining liquid in the syringe. For the second test, take the ready-made reagent solution for the KH keeper into the syringe and continue measuring with this solution, then compare the remaining amount of liquid in the table.
Check the correct concentration of the reagent for the KH keeper / KH keeper Plus, using the Reef Factory KH Smart test kit.
Carry out a standard KH test of the aquarium water according to the instructions.
Take 5 ml of water from the aquarium using a syringe and pour into the vial.
Shake the dropper with KH Reagent 1, then add 2 drops of liquid to the test tube.Carefully stir the solution in a circular motion. The liquid in the test tube should colour green.
Thread the dispensing needle onto a 1 ml syringe.
Draw in 1 ml of KH Reagent 2 liquid. The tip of the plunger should indicate exactly 1 ml. NOTE: air between the fluid and the plunger does not affect the correctness of the test.
Using a syringe with a dispensing needle, drop by drop, add KH Reagent 2 directly to the fluid in the tube so that it does not remain on the walls. Stir the tube after each drop and observe the colour change.
The green solution will gradually begin to change to a transitional grey-brown colour. When you notice that the liquid has become amaranth (purple) - stop the droplet.
Read the value of the remaining KH Reagent 2 liquid in the syringe as indicated by the syringe plunger and note this as value A.
Perform a KH test of the aquarium water using the KH Reagent according to the instructions.
Take 5 ml of water from the aquarium using a syringe and pour into a vial.
Shake the KH Reagent 1 dropper and then add 2 drops of liquid to the test tube.Carefully stir the solution in a circular motion. The liquid in the test tube should colour green.
Thread the dispensing needle onto a 1 ml syringe.
Draw 1 ml of the finished reagent solution into the KH keeper. The tip of the plunger should indicate exactly 1 ml. NOTE: air between the liquid and the plunger does not affect the correctness of the test.
Using a syringe with a dispensing needle, drop by drop, add the KH keeper reagent solution directly to the fluid in the tube so that it does not remain on the walls. Stir the tube after each drop and observe the colour change.
The green solution will gradually begin to change to a transitional grey-brown colour. When you notice that the liquid has become amaranth (purple) - stop the droplet.
Read the value of the remaining KH Reagent 2 liquid in the syringe as indicated by the syringe plunger and note this as value B.
Compare the A value and the B value to the table. If the values correspond to one row in the table, this means that the KH Reagent for KH keeper Plus has the correct concentration.
Example 1: Value A is 0.47 ml, value B is 0.41 ml and they correspond to one row in the table. This means that the reagent has the correct concentration.
Example 2: Value A is 0.47 ml, value B is 0.44 ml and they do not correspond to one row in the table. This means that the reagent does not have the correct concentration.
Checking the correct concentration of the reagent for the KH keeper / KH keeper Plus, using the Salifert KH/Alk drop test.
Perform a standard KH test of the aquarium water according to the instructions provided with the Salifert KH test kit. Record the remaining amount of liquid in the syringe and note this as the A value.
Perform the KH test of the aquarium water according to the instructions, but instead of the reagent from the kit, take the ready-made reagent solution for KH keeper / KH keeper Plus into the syringe and continue the test. Record the remaining amount of liquid in the syringe and note it as value B.
Compare the A value and the B value to the table. If the values match one row in the table, this means that the KH reagent for KH keeper Plus has the correct concentration.
Example 1: Value A is 0.46 ml, value B is 0.41 ml and they correspond to one row in the table. This means that the reagent has the correct concentration.
Example 2: Value A is 0.46 ml, value B is 0.44 ml and they do not correspond to one row in the table. This means that the reagent does not have the correct concentration.
