Di Pacci — Water Testing — USA

Aquasonic Carbonate Hardness (kH) Test Kit — Freshwater & Saltwater Aquariums

This kit measures carbonate hardness (kH), also called alkalinity or acid-binding capacity, in aquarium water. It is made for freshwater and saltwater fish tanks, not for testing water feeding a coffee or espresso machine.

You add a reagent to a water sample drop by drop until the color changes, then count the drops to read the kH level. A stronger carbonate hardness reserve helps keep aquarium pH stable and can act as a backup carbon dioxide source for aquatic plants and algae.

About This Test Kit

Is this kit for coffee machine water, or aquarium water?
It is an aquarium water test kit, made for freshwater and saltwater fish tanks. It does not test water hardness for espresso machines or other coffee equipment.
What does carbonate hardness (kH) tell me?
It measures the carbonate and bicarbonate content of a water sample, also called alkalinity or acid-binding capacity. This affects how stable the water's pH is and can supply carbon dioxide to aquarium plants and algae.
How do I use the test kit?
You add the kit's reagent to a water sample drop by drop until the sample changes colour, then count the drops to get the kH reading. Follow the exact dosing and colour-match steps printed on the kit's own packaging.
How many tests does one kit include?
Approximately 125–250 tests, per the product listing. We have not been able to independently confirm this figure against the manufacturer's own specification, so treat it as approximate.
