Inga vettiga instruktioner på vattentester?!

[Thomas_W]

Hej hopp!

Har nu precis fått hem alla vattentester jag beställt från Drakfisken. Har hittills bara kunnat testa nitrit och nitrat, då all min övriga testutrustning har varit endast för sötvatten. Döm då om min förbannelse, när jag idag äntligen får hem test för KH, PH, CA och MG, och märker att instruktionerna för de två sistnämnda ENDAST är på tyska, franska och holländska! Nog för att jag var rätt bra på tyska i skolan, men när det gäller "fackspråk" av det här slaget litar jag nog endast på min engelska, alternativt modersmål. Märket på testerna är Salifert, vad fan gör jag nu? Finns det någon hemsida på nätet där man kan läsa instruktionerna översatta till engelska eller svenska?

CA

1. Add with the syringe 2ml of water in the test vial. For a lower resolution and more test per kit add 1 ml instead of 2ml.

2. Add 1 level spoon of Ca-1 (low resolution approx 1/2 sppon) Do not mix it yet.

3. Add 8 drops of Ca-2. The low resolution mode requires 4 drops. Swirl ( do NOT shake) for 10 seconds.

4. Put the plastic tip firmly on the 1 ml syringe. And draw into the syringe the CA-3 reagent (ensure that the end of the plastic tip is constantly submersed in the Ca-3 reagent) till the lower end of the black part of the piston is axactly ath the 1.00 ml mark. There will be some air present just below the piston. This is the air which was present between the end of the plastic tip and the piston. This will not influence the test result.

5. Add dropwise with the 1 ml syringe the Ca-3 reagent to the water in the test tube. Swirl after each drop a second or two. Continue with this until the color changes from pink-red to a clear blue color.

6. Hold the syringe with the tip facing upward and read the position of the, now the upper end, of the black part of the piston. The syringe has graduations of the 0.01 m. Read the calcium value from the table or calculate as follows.

ppm Ca = (1-reading in the step 6) x 500

If you have chosen for the lower resution multiply the calculated result by 2.

Natural sea water contains 400-425 ppm calcium. Use Salifert's Coral Calcium for good results.

MG:

1. Add with the 2ml syringe 2ml of water to the test vial.

2. add 4 drops of MG-1 and swirl gently for 30 seconds.

3. Add one spoon of Mg-2 powder (spoon inside) to the test vial and swirl for 10 seconds.

4. Place the plastic tip firmly on the 1ml syringe and draw into this MG-3 reagent until the lower end of the black syringe part is at the 1.00 ml mark. Ensure that during this that the plastic tip is submersed in the Mg-3 reagent to avoid that air bubbles are withdrawn instead of liquid.

An air layer between the liquid and the piston is normal. This is air which was present between the end of the tip and the piston, this will not influence the result.

5. Start adding the Mg-3 reagent with the 1 ml syringe to the test vial until the color changes to gray or blue (whichever color is observed first).

Do this drop wise and swirl after each drop for a second or two.

6. Hold the syringe with the tip facing upward and read the position of the upper end of the black syringe part.

Each division corresponds to 0,01 ml.

The magnesium concentration can be obtained from the table or by use of the following equation:

ppm Mg = (1 - reading step 6) x 1500

Natural sea water has a magnesium concentration of approx 1300-1500ppm. The cencentration varies with salinity.

Too low magnesium concentration makes maintaining correct and alkalinity concentration difficult. Magnesium cencentration can be incread with Salifert's magnesium.
