API GH & KH TEST KIT
API has been an aquatics industry leader for over 50 years, and we are committed to developing the best products and solutions to simplify the care of aquariums and ponds.
GH & KH Test Kit
Water hardness is a measure of the dissolved mineral content of water. There are two types: the general hardness (GH) and carbonate hardness (KH).
When keeping freshwater fish and plants, the GH and the KH of aquarium water should match their natural habitat. The GH & KH TEST KIT helps aquarists duplicate the natural habitat of their fish, as well as detect low KH levels, which can lead to rapid and wide pH shifts, stressing fish.
Tip: KH can strongly influence pH. If you add a pH adjuster to your aquarium and the pH returns to its original level in a day or two, this is called “pH rebund” –and it is caused by high KH.
Very hard water can cause an ugly white crust (scale) to form on the hood, on glass walls, and on other parts of the aquarium.
Kit contains 2 bottles of liquid reagent, 2 glass test tubes with snap-tight caps, step by step instructions and information on how to correct unsafe conditions.
- Monitors GH & KH to create a more natural habitat

I know some have said the colors are hard to distinguish. I didn't find that to be true. The colors are pretty light, but as long as the tube is up against a white background it is pretty clear if the GH one is pale green or pale orange, or the KH one is blue or yellow. If you are mildly colorblind this might be rather hard.
Being a titration test, you basically add one drop, shake it, and look at the color. Repeat until it changes, counting drops. This is fine for me, but if you have very high hardness it might take a while to run the test. My tap is 7dGH and 5dKH, and I raise the GH to 10. 10 drops doesn't take too terribly long.
This is an important test kit to get if you have any interest in keeping even slightly difficult fish. If you are doing CO2 injection, too, you'll need a kit like this because the pH can jump around with CO2 injection, and so you'll need to know what's happening with the KH.
This kit will last A LOT longer if you have soft water. That's because you get your readings by adding one drop at a time. So if you have really hard water, you'll need, say, 10 drops until you get a positive result. If you have soft water, you may only have to add 2-3 drops to get your positive result.
I have one issue with this product, but it's not the product's fault. It's Amazon shipping's fault. This kit arrived with the GH bottle's cap half off, and it was leaking through the package.
This works well and I'm glad to add it to my tool kit.
You still have to buy the KH, GH test kits seperately. Although these are Not included in the Master Test Kit ( I have always wondered why) the KH / GH tests are equally important to your pond balance and maintenance.
It would get 5 stars if the GH reagent were to actually make it to the expiration date. For the price it's still a very good value, just note to replace the GH reagent earlier than the expiration.
Hopefully just a bad lot and will be returning for another set.
