Description

This kit combines the Marine pH & Alkalinity, Ammonia, and Nitrite & Nitrate kits into one kit. MultiTest™ Marine Basic performs over 75 tests and contains reference samples for validation.

Marine pH & Alkalinity ALK

The Marine pH & Alkalinity test features a unique dye that has a pronounced color change between 8.0 and 8.3, making it the easiest kit on the market to read in that critical range. It is suitable for marine or brackish water only. Alkalinity may be read from the same sample in 0.5 meq/L increments.

Ammonia

The ammonia test 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 and thus it is much more important to keep an eye on the level of free ammonia in your system. This test may be used with freshwater or marine water.

Nitrite/Nitrate NO2 NO3

The Nitrite/Nitrate test measures nitrite to less than 0.1 mg/L and nitrate to less than 0.2 mg/L in marine or freshwater. The values reported are expressed as nitrite and nitrate rather than nitrogen (to convert to nitrogen, simply divide by 3.3 and 4.4, respectively).

75 Tests

MultiTest™ Marine Basic performs over 75 tests each of marine pH and alkalinity, ammonia, and nitrite/nitrate

And with the multi-cavity test plate, multiple tests can be run at the same time.

Accuracy

Range

pH: 7.80–8.70
Alkalinity: 0–∞
Ammonia: 0–6 mg/L
Nitrite: 0-25 mg/L
Nitrate: 0–50 mg/L

Precision

Detectable changes on the color chart in the following increments:

pH: 0.01 pH units
Alkalinity: 0.5 meq/L
Ammonia: 0.01–0.1 mg/L
Nitrite/Nitrate: 0.1–1 mg/L

Reference Sample

It isn't necessary to run a reference test to use this kit; however, its proper performance can be validated by running a test in the normal manner except that the reference sample is used in place of aquarium sample. You might choose to run a reference test if you have cause to believe the test is giving incorrect results. If you run a test using the reference sample and obtain the correct result (based on the known reference value provided) then you can safely be sure the test is giving accurate results.
