Aquarium Pharmaceuticals, API, MARS Fishcare Gh and Kh Test Kit

This is an essential test kit for fish keeping as it will determined the general hardness and carbonate hardness in the water. I use ro water for my fresh water tanks which gives the pure form of water. Then I mix general hardness enhancing solution like seachem equilibrium or seachem replenish to make water with desired gh level. Then I use seachem alkaline buffer and acid buffer accordingly to maintain the proper carbonate hardness and ph for the specific species tank I'm using the water. This kit comes handy in checking the final gh and kh levels before adding the water in the tanks..

Very accurate and extremely easy to use. I use RO water for my aquarium and these readings help me maintain my parameters as desired. Very good product!

I purchased this kit thinking that it will be very useful in aquarium water testing, and I used it a couple of times. It helps in determining the hardness and type of hardness, of the water used to keep fish, but honestly now I feel it was a needless purchase, because once you know about the hardness of the water the kit is not of much use again. Afterall we do not use different sources for the aquarium water, almost all of us use the same source after deciding the suitable water or mix of water from different sources. Being said that, I found the kit is very dependable and results are accurate. Even though I used only a couple of times it has helped me in deciding which plants and fish are suitable for the water which I use in my aquarium tanks, and whenever I had bought not heeding the results those fish perished and plants did not flourish!

Works as expected. The results have to be counted in drops of the solution added to the water and wait for color change. The chart comparison provided is in degrees, instead of drops counted. There might be a bit of confusion at first, but its not that difficult to understand. Very costly but i guess that's what you need to pay to know the water quality with such accuracy and also there aren't many options either.

Great product and very useful to have around

The API test kit is great ... but giving 3 stars because I received an opened box pack without the test documentation or instruction manual. Had to fig out on the internet how to get it working .... could have retured the kit but was on a schedule to complet my aquarium, hence decided against the return. Expiry date is also only about a year and hence it definetly shows its an old pack. Please check my pics as it clearly shows that the package was opened and cellotaped before sending to me. Pay for a new pack and this is what we get!

first time reviewing product on amazon. good product expiry data is till 2019. Works brilliant and easy to use. Pakaging should be better. Nothing damaged.

No wonder got best result from the market leader.

easy to use and accurate. good to monitor hardness in fresh water aquarium

Superb product. API is one of my resources for many of my aquarium essentials. Never had any problem with any of there items. Great value for money, with many products giving you size options for what you need. All products from medicated to water parameters and plant care.

Easy to use and readings of both gh and kh very accurate no guessing or matching colours

Muy bien producto a precio racionable, dar bien mediciones comprobado contra otras test kits mucho mas caro y todos muestra la misma nivel de GH y KH. Muy facil de usar aunque con agua muy blanda como el mio hay que mirar desde arriba contra algo blanco para ver el color de inicio en test GH.

I recently started using the API GH & KH Test Kit for my freshwater aquarium, and I must say it has been an incredibly helpful tool for maintaining a healthy tank environment. Here’s a detailed review based on my experience: **Ease of Use:** The test kit is very straightforward and user-friendly. The included instructions are clear and easy to follow, even for beginners. Testing both General Hardness (GH) and Carbonate Hardness (KH) takes just a few minutes, and the color changes in the water make it easy to get accurate results. **Accuracy:** The API test kit provides reliable and consistent readings. I compared the results with a digital meter, and they matched up perfectly. Knowing the GH and KH levels helps me adjust my water chemistry for optimal conditions, especially for sensitive fish like cichlids and shrimp. **Functionality:** Having a tool that measures both GH and KH in one kit is incredibly convenient. GH helps monitor essential minerals for fish health, while KH is crucial for stabilizing pH levels. This kit makes it easy to detect changes early, helping prevent pH swings or stress in my fish. **Value for Money:** For the price, you get a high-quality, reliable kit that will last quite a while. The included bottles have enough solution for numerous tests, making it a cost-effective option for regular water monitoring. **Overall Impressions:** The **API GH & KH Test Kit** is a must-have for any freshwater aquarium enthusiast.
