Simple test to check total general hardness content in water.
1 x Measuring Syringe
1 x GH test Reagent 1 (5g)
1 GH test Reagent 2 ( 10ml)
1 x Dosing Spoon
1 x Instruction manual
1) Wash the vial carefully before using
2) Add 5ml sample water into the vial
3) Add 1 sccop of reagent 1 and swirl for 10 seconds
4) Add reagent 2 drop by drop until the colour change from pink-red to blue.
5) Number of drops = level of GH ( Total Hardness)
We recommend testing for GH once a week in soft water areas, and once every 2-3 weeks in hard water areas. Always read the instructions carefully before using. If GH levels are unsatisfactory then you should seek advice as to the underlying cause.
