Fauna Marin Multi Reference 100ml

With the Fauna Marin multi-reference solution it is possible to test your water tests under real conditions. The solution is not made from freshwater, but the ion spectrum has been adjusted according to the test media, the salts and elements are in proportion and concentration similar to seawater. 

The 100 ml solution is stable and combines all these values ​​in one solution (note: the values ​​vary depending on the batch - the exact values ​​are on the respective multi reference!):

Calcium 422 mg / l 
Magnesium 1315 mg / l 
Potassium / pottasium 409 mg / l 
Salinity 35 psu / 53.0 mS (25 ° C) 
dKH 6.6 / 2.35 meq / l 
Strontium 8 mg / l 
Nitrate 10 mg / l l 
PO4 0.2 mg / l
 

A review of your own hobby water tests is useful if:

• a test was purchased new.

• unexpected readings occur.

• Tests were stored for a long time from opening.

• the durability tends to end.

The measurement with the sterile reference solution is carried out normally. The measured value is compared with the reference solution and set in relation. This ratio is the correction value for the normal measurements with the aquarium water.

Example:

The measurement of the reference solution with a magnesium test gives: 1000 mg / l

However, the reference solution contains: 1314 mg / l

The ratio is: 1314 mg / l: 1000 mg / l = 1.314

This correction factor is noted on the magnesium test.

A subsequent measurement with this magnesium test gives the pool water: 1300 mg / l

Calculation: 1300 mg / l * 1.314 = 1708.2 mg / l
