API Freshwater Master Test Kit, Kit includes laminated color card, 4 test tubes & holding tray

Product Information

This is exactly the same 9 parameters as the Sera Aqua Test Box offers, except for a calcium test in place of the copper tests, which makes it useful for reef tanks and planted tanks! Another fairly comprehensive kit, the Nutrafin Master Test Kit for freshwater and saltwater tanks includes Hagen tests for pH, KH, GH, ammonia and ammonium, nitrite, nitrate, phosphate, iron, and calcium.

Cap the test tube and invert tube to mix solution. Do not hold finger over open end of tube as this may affect the pH of the test solution. Some users have expressed frustrations over test tube caps coming loose and slightly vague color cards, but in general, this is a well-made kit that’s especially useful for marine and reef tank users. Things We Like: In marine tanks, even low levels of phosphates can be problematic, encouraging harmful algae, and causing corals to turn brown. Iron (Fe) The API® SALTWATER MASTER TEST KIT measures the 4 most important saltwater parameters – pH, ammonia, nitrite, and nitrate – to enable easy testing of your tank’s natural cycle, and to aid in maintaining a thriving saltwater aquarium. Testing is fast, easy, and accurate, yielding precise results, and comes with 4 test tubes and a convenient holding tub for easy storage. This kit also includes a complete, step-by-step instructional booklet with a color chart that provides information on how to correct unsafe water conditions. Each SALTWATER MASTER TEST KIT will conduct 550+ tests, so you can get the most out of your kit for years of fast, accurate water testing.Copper tests are useful when treating fish with copper-based medications, and iron tests are important for diagnosing iron deficiency in live plants.

Along with the usual water parameter tests, phosphate tests are useful for controlling algae levels, as well as for coral reef aquariums. If you’re looking to get more accurate readings from the most reliable source, though, then API liquid test kits are the way to go. If you’re carrying out lots of tests, they’ll likely save you some money too. Not surprisingly, you have to pay for all the extra tests, so this kit is substantially more expensive than the standard 4-in-1 liquid test kits. Things We Like:

Customer reviews

When you set up a new aquarium, it needs to go through a period known as ‘cycling’ before it’s ready to use.

Read the test results by comparing the color of the solution to the appropriate Nitrate Color Card (choose either Fresh water or Salt water). The tube should be viewed in a well-lit area against the white area of the card. The closest match indicates the ppm (mg/L) of nitrate in the water sample. Rinse the test tube with clean water after use.
