Contains one (1) API GH & KH TEST KIT Freshwater Aquarium Water Test Kit, including 2 bottles of testing solution and 2 glass test tubes with cap.
Helps monitor water quality and prevent invisible water problems that can be harmful to fish and plants and cause fish loss.
Accurately measures GH & KH in freshwater aquariums.
Water hardness is a measure of the dissolved mineral content of water and should match fish natural habitat to prevent fish stress and keep them healthy.
Use for weekly monitoring and when water or fish problems appear.
Front of package indicates “for FRESH WATER” because this is the most common use of this product, but instructions include ranges for marine and brackish aquarium water. So this product does not need a warning and it can be used if they wish to..

Easy to use test drops for measuring the Hydrogen concentrates dissolved under its own pressure into a water state..
Each drop represents 0.10 PPM (100 PPB) of Hydrogen gas dissolved under pressure into a water state using a 6 ml sample of water in the plastic beaker included..
Best way to test how efficient your Hydrogen Water Machine dissolves the H2 into a concentrate in water. Not intended to measure H2 in water that is not dissolved under its own pressure. Hydrogen concentrates are measured by calculating in PPM measurements. .Contains approximately 400 drops and good for 25 to 40 tests depending on levels achieved..
We sell these test drops because unlike others, we want you to test our Hydrogen Water Makers for their performance. We only ask that you contact us immediately if you get results that are not in the range we specify for the product..
