Fauna Marin Multi Reference Water test – 100ml

Our Reference Solution is the first to be based on a saltwater matrix and is quality tested using our ICP-AES testing machine. We use a saltwater matrix that is similar to aquarium water so that all common variables which affect normal water tests are taken into account.

Each batch is quality controlled and tested in our Seawater Research Laboratory to ensure accurate and reliable solutions, every time.

Our 100ml solution is stable and combines all these values into a single solution – the values vary with each batch! Please check your Multi Referenz bottle for the respective values.
Calcium – 422 mg/L
Magnesium – 1315 mg/L
Potassium – 409 mg/L
Salinity – 35 ppt (53,0 mS) @ 25°C
Alkalinity – 6,6 DKH (2,35 meq/L)
Strontium – 8 mg/L
Nitrate – 10 mg/L
Phosphate – 0.2 mg/L

Multi-Reference Solution is especially useful for
Testing the validity of new test kits
Verifying results after unexpected test results
Testing kits that were stored for a long time
Checking an expired test kit’s accuracy
Calibrating your refractometer
Example
Measurement of the reference solution with a magnesium test gives you a result of 1,000 mg/L.

The reference solution however contains 1,314 mg/L
The ratio therefore is: 1,314 mg/L : 1,000 mg/L
The correction factor is noted on the magnesium test
A later measurement with this magnesium test results in the aquarium water: 1,300 mg/L
Calculation: 1,300 mg/L * 1.314 = 1,708.2 mg/L
