Har købt et testsæt i strontium (salifert), men brugsanvisningen er på hollandsk.

er der ikke en, der har et link til en sådan

Strontium + Calcium Profi Test

For marine water only.

Warning:
Reagent Sr-l is caustic. In case of contact with eyes rinse immediately with plenty of water and contact a physician immediately. In case of ingestion do not induce vomiting but contact a physician immediately. In case of contact with skin wash with plenty of water.
Keep out of reach of children!

General information
Salifert has been the first to offer a -.strontium.tes tkit. Jhisis -the thirdversio n and has been improved. The color change is better, number of steps have been reduced and accuracy and precision have been improved as well.
Strontium, however, remains difficult to measure because it resembles calcium in many respects and is present in a far lower concentration than calcium.
You can compare it with trying to find 10 slightly off-white marbles between 800 white marbles. '

Strontium is a very important element and assists many corals and calcareous algae
to grow. Strontium is next to calcium and carbonate (alkalinity) the most abundant element found in skeletal material of corals. Natural seawater contains approx. 7 - 9 mgiL (= ppm) strontium. In reef tanks values between approx. 10 and 15 mgiL are excellent.
Ifpossible conduct a strontium measurement once or twice a month, depending on coral growth (strontium depletion rate).
Calcium is present in natural seawater in a concentration of approx. 400 - 450 mgiL. Alkalinity should be approx. 8 dKH (use our alkalinity test kit)
Strontium concentration can be increased and maintained with Salifert Strontium. For the sake of just maintaining strontium concentration together with calcium and trace elements, Salifert Coral Grower can be used.
I9jncreas~ @~~mta~g}.9jym~ concentration Salifert Coral Calcium can be used. Or just for maintaining calcium, together with strontium and trace
elements use Salifert Coral Grower.

Caution
Using the wrong syringes can spoil the reagents and can lead to inaccurate results. The tables which are included in this instruction can vary from batch to

batch so use only the instructions which came with this particular test.

Cleaning
After use rinse the test vial several times with wanii water. If some material keeps adhering on the walls fill the test vial with vinegar. Rinse after a few minutes several times with water.
Clean the scoop with water and make it dry with some tissue.
Empty the syringes after use. Remaining reagent can be put back (do not put back the reagent in a wrong bottle! I). Never rinse the syringes with water.

2] Add 12 drops 8r-1 (caution caustic!) and swirl gently for 10 seconds.

3] Add 1 level scoop of Sr-2 and swirl gently for 5 seconds. The color should be red/pink

4] Fit the 1 m1 syringe without the yellow \abel with the small plastic tip. Ensure that the tip is mounted firmly.
Fill this syringe with 1 m1 of Sr-3 (lower end of black rubber ring at 1.00 m1 mark) Dose this amount in the test vial end swirl gently for 20 seconds. If the color has changed to blue and remains so even after an additional 30 seconds then the calcium concentration is far too low (approx. 300 mg/L or less) and should be corrected first before doing strontium testing.

5] Ag~ fill this syringe with 1 ml of Sr- 3. Add this drop wise to the test vial.
Swirl gently for a few seconds after each drop until theoolor changes to blue.
lfthe color has changed to blue then swiJI gently for 15 seconds. It is very likely~tfiat the color will revert back and will not be pure blue. In that case add one more drop of Sr-3 and swirl again for 15 seconds. Repeat this until the color remains blue.

6] Hold the syringe with the plastic tip
l~cing !l-P~':I:.!!J. Read th~ v&~ ;it ~e
upper part of the black robber ring. Look for this value in the calcium table to get the calcium concentration.

7] Fill the 1 m1 syringe with the yellow label (no plastic tip needed and is not supplied) with 0.5 m1 Sr-4 (lower end of black robber ring at 0.50 m1 mark. Add this to the test vial and swirl gently for 10 seconds. The color will now be red/pink.

8] Add two level scoops of Sr-5 and swirl gently until this powder has dissolved

Let it stand for 12 - 15 minutes (use a clock).

9] Fill the 1 m1 syringe without the yellow label and fitted with the plastic tip with 1 m1 of Sr-3. Add this drop wise to the test vial. Swirl gently for 20 seconds (should definitely not be less than 20 seconds!) after each drop until the color changes to blue.
