Zoobest Alpha Test Total Hardness - TH

Water test for determining the total hardness (GH - permanent hardness) - suitable for freshwater and marine aquariums

Total hardness test set Instructions for use

1. rinse the measuring vessel with the water to be tested and fill up to the mark (corresponding to 5 ml). *
2. add one drop of reagent and swirl. If hardness is present, the sample will turn red.
3. Add the solution from the dropper bottle drop by drop until the colour changes from red to green.
   Swivel the measuring vessel after each drop. Count the drops!
   1 drop = 1°dH
4. The sensitivity of the test can be increased by doubling the sample volume to e.g. 10 ml. Each drop of the test solution then corresponds to 0.5° dGH.

* The meniscus of the water surface must exactly touch the 5 ml calibration line.

Caution

Clean the vial after use, close the reagent bottle tightly and store in a cool, dry place away from light.
Keep out of reach of children!
