Poor water quality can cause fish stress, illness and even loss. Most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly. Testing aquarium water weekly will aid in keeping your most important water parameters within the proper range for your aquarium. Choose from a wide range of API testing options, such as our popular FRESHWATER MASTER TEST KIT or 5-IN-1 TEST STRIPS, for accurate water evaluation. Regular testing will help you easily determine your aquarium conditions. Find Your Ideal Testing Style! Your API Test Options Choose the test method that works best for you. Whether you’re a bit pressed for time, or you prefer to measure your parameters on a more in-depth scale, or you only need to test one or two specific parameters, API has what you need! Dip and Read Just dip a 5-in-1 TEST STRIP in your aquarium, swirl twice, and compare to our color chart for fast and accurate results. The Scientific Approach For more detailed analysis, use the FRESHWATER MASTER TEST KIT, POND MASTER TEST KIT, SALTWATER MASTER TEST KIT, or REEF MASTER TEST KIT for precise readings of parameters.

Review: Great product - Works perfectly highly recommended Review: API is easier to use - Cost is high ## Features - Calcium is one of the most important elements in a reef aquarium. Reef invertebrates, such as corals, crustaceans, mollusks, and even some type of encrusting algae, need calcium to grow and remain healthy. Over time, the calcium level drops as it is used by invertebrates, or as it reacts with excess phosphate. The API CALCIUM TEST KIT measures calcium levels as low as 20 mg/L to help you keep your reef inhabitants healthy. - Contains 2 test bottles, easy-to-ready instructions, and glass test tube - Do I need to test calcium parameters in a freshwater aquarium? No, calcium levels need to be monitored and maintained in reef or marine aquariums, as improper levels can be harmful to corals and crustaceans. - For best results, test calcium levels with API CALCIUM TEST KIT in your saltwater tank weekly. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0006JDWHI | | Allergen Information | BPA-Free | | Best Sellers Rank | #3,682 in Pet Supplies ( See Top 100 in Pet Supplies ) #53 in Fish Medication & Health Supplies | | Brand | API | | Brand Name | API | | Country of Publication | USA | | Customer Reviews | 4.5 out of 5 stars 683 Reviews | | Global Trade Identification Number | 00317163120699 | | Item Form | Liquid | | Item Type Name | Aquarium Test Kit | | Item Weight | 68.04 Grams | | Item form | Liquid | | Item weight | 68.04 Grams | | Manufacturer | Aquarium Pharmaceuticals | | Manufacturer Part Number | 69L | | Model Number | 69L | | Number of Packs | 1 | | Target Species | Invertebrates | | UPC | 317163120699 | | Unit Count | 1 Count | | Unit count | 1 Count | ## Images ![Calcium Test Kit Saltwater Aquarium Water 1-Count Kit, 69L (69L) - Image 1](https://m.media-amazon.com/images/I/61r4L5M4AzL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by N***D on 27 June 2026* Works perfectly highly recommended ### ⭐⭐⭐⭐⭐ API is easier to use *by C***H on 11 June 2020* Cost is high ### ⭐⭐⭐⭐⭐ Five Stars *by R***C on 9 October 2015* Great product for testing.
