APICOPPER TEST KIT 90-Test Aquarium Water Test Kit

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. It’s easy to use, highly accurate, and helps ensure your water parameters are within the right range for your fish and plants to thrive. I highly recommend it for hobbyists of all experience levels.**Rating: 5/5**Reliable, accurate, and easy-to-use water testing for a healthy aquarium!

This is about the easiest phosphate test kit I have ever used, and the company that makes them has really great customer service. One of the test tubes arrived broken (not a huge deal, there are two in the package) so I reached out to the customer service email to see if they had extras available for purchase. They took a while to get back to me, but were very apologetic about the wait and went above and beyond to make it right. They sent me a brand new test kit, and a hand-written note expressing their apologies for taking a few extra days to get back to me.I, myself, work in customer service, so I have pretty high standards for how I am treated as a customer. This company exceeded my expectations and then some, and the product they make is, in my humble opinion, one of the best available.I can't wait to try some of their other products, because I really do believe that if I ever have any issues they will be sure to make it right. I actually haven't really had issues with this phosphate test, it seems very accurate and the user experience is significantly better than competing tests. It's easy to read, with a nice, clear color card, and very clear instructions. A+ product, A+ customer experience. Well done!

The colors seem easier to differentiate than previous test.

these worked great. made it very easy to dial in tank water.

This is my go to test kit for calcium. It is easy to use and the color change is readily discernable. I cant comment on accuracy of the test, but I am able to generate consistent numbers. The reason that I rate this at 4 rather than 5 is because each test requires 10 drops of reagent 1. However, for each test if you have typical levels of calcium in your reef, one would use 20 drops (roughly) of reagent 2. This means that you will consume all of reagent 2 and only about half of reagent 1. All API would need to do is increase the volume of reagent bottle 2 (and charge a little more) to get more tests from the kit.

Great product

Much better than the API test strips! This test kit was absolutely worth the money.

Useful for measuring your water parameters. Especially when cycling your aquarium.
