## Description

Keep your aquatic life healthy and thriving by testing your aquarium water's calcium levels regularly with this easy-to-use API CALCIUM TEST KIT for aquariums.Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. Calcium is one of the most important elements in a reef aquarium. Reef invertebrates such as corals, crustaceans, mollusks and even some types of encrusting algae need calcium to grow and remain healthy. Over time, calcium levels drop as invertebrates use calcium in aquarium water. The API CALCIUM TEST KIT measures calcium levels as low as 20mg/L. It contains two calcium test bottles, capped test tube and instructions. For use in reef aquariums.  With API aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium.

### ⭐⭐⭐⭐⭐ helpful tool for maintaining a healthy tank environment
*by R***O on December 17, 2024*

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.
