What can I do when the measured value of a water test falls outside the scale?
If one of your measurements reaches the end of the colour chart scale you can multiply the scale by diluting later tests with distilled water (e.g. JBL Dest). _x000D_ _x000D_ Here’s how to do it: dilute the sample with distilled water and carry out the test once more. _x000D_ _x000D_ This works in detail as follows: _x000D_ GH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH. _x000D_ KH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH. _x000D_ _x000D_ Note: when using 10 ml sample water the colour development is weaker with the first drops than with 5 ml sample water. Put the measuring container on a white underlay for a better readability. _x000D_ _x000D_ NH4/NH3 ammonium/ammonia, NO2 nitrite, Fe iron and Cu copper: _x000D_ 2.5 ml sample + 2.5 ml dist. water: result times 2 _x000D_ 1 ml sample + 4 ml dist. water: result times 5 _x000D_ 0.5 ml sample + 4.5 ml dist. water: result times 10 _x000D_ _x000D_ NO3 nitrate, SiO2 silicate, PO4 phosphate sensitive and Mg magnesium freshwater: _x000D_ 5 ml sample + 5 ml dist. water: result x 2 _x000D_ 2 ml sample + 8 ml dist. water: result x 5 _x000D_ 1 ml sample + 9 ml dist. water: result x 10 _x000D_ _x000D_ PO4 phosphate koi high range: _x000D_ 2.5 ml sample + 2.5 ml dist. water: result x 2 _x000D_ 1 ml sample + 4 ml dist. water: result x 5 _x000D_ _x000D_ K potassium: _x000D_ 7.5 ml sample + 7.5 ml dist. water: result x 2 _x000D_ 3 ml sample + 12 ml dist. water: result x 5 _x000D_ 1.5 ml sample + 13.5 ml dist. water: result x 10 _x000D_ _x000D_ K potassium in marine water: _x000D_ 1. Fill 10 ml of sample water with distilled water to 300 ml. _x000D_ 2. Follow the instructions for fresh water. _x000D_ 3. Multiply the test result by a factor of 30._x000D_ _x000D_ CO2 direct, Ca calcium and Mg+Ca magnesium+calcium: not required._x000D_
