Protect marine fish and invertebrates from unsafe water conditions with API SALTWATER MASTER TEST KIT. Fish waste, uneaten food, plant refuse and other organic compounds can create harmful levels of ammonia, nitrite and nitrate as well as cause drastic fluctuations in pH. These unhealthy conditions can result in fish stress, gill and tissue damage and even death. The API SALTWATER MASTER TEST KIT accurately measures these four saltwater parameters that are key to keeping your aquarium healthy. It includes six bottles of liquid test reagent, four glass test tubes with snap-tight caps, a holding tray and a step-by-step instruction booklet with information on how to correct unsafe water conditions. Simply fill a clean test tube with 5 ml of water, add the appropriate test drops and compare results with the color chart. Then follow the recommendations to modify conditions if action is needed. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium.

Testing the Waters

In order for fish to thrive, water must be similar to that which could be found in their natural environment. 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.

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.

Product description

Calcium presence in water supplies results from passage over deposits of limestone, dolomite, gypsum and gypsiferous shale. Its concentration may extend from 0 to several hundred milligrams per liter, depending on its source and treatment. Calcium is necessary in plant and animal nutrition since it is an essential constituent of bones, shells and plant structures. Calcium in water as carbonate is one of the primary components of water hardness which can cause pipe or tube scaling. The HI 758 Calcium Checker HC is extremely simple to use. First, zero the instrument by adding Reagent A, deionized water and 0.1 mL of sample into the vial. Insert into the HI 758 and press the button. Next, remove the vial and add Reagent B and shake to dissolve. Reinsert into the Checker HC and press the button to read the calcium concentration in ppm on the display. Use for quick and accurate on the spot analysis. Single button operation: zero and measure. Range: 200 to 600 ppm. Resolution: 1 ppm. Accuracy at 25 degree C: +/-6% of reading. Light Source: light emitting diode at 610 nm. Light Detector: Silicon Photocell. Environment: 0 to 50 degree C (32 to 122 degree F); max 95% RH non-condensing. Battery Type: 1.5V AAA. Auto-off: after 10 minutes of non-use. Dimensions: 81.5mm x 61mm x 37.5mm (3.2" x 2.4" x 1.5"). Method: adaptation of the zincon method.

• Easier to use and more accurate than chemical test kits, less expensive than professional testing
• Accuracy +/-6 % of reading at 25 degree C / 77 degree F

The HI772 Checker®HC (Handheld Colorimeter) provides a simple, accurate, and cost-effective way to measure alkalinity in degrees of carbonate hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity. Designed as a more accurate alternative to chemical test kits, the HI772 provides quick, accurate results in a few easy steps.

Keep your fish healthy and thriving by testing your aquarium water's NO2 levels regularly with this easy-to-use API NITRITE TEST KIT for freshwater and saltwater aquariums. Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. Nitrite is produced in the aquarium by fish waste and uneaten fish food.

Product description

This kit measures total (NH3 and NH4+) and free ammonia (NH3 only) down to less than 0.05 mg/L and is virtually interference free in marine and fresh water. Free ammonia is the toxic form of ammonia (vs. ionized Ammonia NH4+ which is non-toxic) and thus it is much more important to keep an eye on the level of free ammonia in your system.

This kit is based on the same gas exchange technology that is used in the Ammonia Alert® and thus is the only kit on the market that can read levels of free ammonia while using ammonia removal products such as Prime®, Safe™, AmGuard™ and any similar competing products. The other kits (salicylate or Nessler based) determine the total ammonia by raising the pH of the test solution to 12 or greater. At this high pH all ammonia removal products will breakdown and rerelease the ammonia, thus giving you a false ammonia reading.
