Measures iron to less than 0.05 mg/L Multi-cavity plate for simultaneous testing of up to 6 tests at the same time Includes reference for test validation Marine or Freshwater Iron is of no importance in ?sh only aquaria; however, iron over 0.5 mg/L may be toxic to some species and should be avoided. Under normal conditions, iron is virtually impossible to maintain at measurable concentrations in seawater. Natural seawater concentration for iron is about 0.01 mg/L. Iron is important in planted aquaria and should be maintained between 0.1 to 0.2 mg/L. MultiTest™ Iron measures both ionic and most chelated iron in freshwater or marine water to less than 0.05 mg/L. It performs over 75 tests and contains a reference sample for validation. Features 75 Tests - MultiTest™ Iron performs over 75 tests And with the multi-cavity test plate, multiple tests can be run at the same time. Accuracy Range - Measures between 0–2.0 mg/L iron Precision - Detectable changes on the color chart in 0.05 mg/L increments. 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. Color ChartAll MultiTest™ test kits come with an easy-to-read color chart. It features a 5 cm viewing window to help isolate color and match as closely as possible to the test sample Opaque Multi-Cavity Test PlateAll MultiTest™ test kits are read from an opaque white test plate. The sliding color chart along with the six-cavity test plate allows for easy reading and comparisons of several samples at the same time.
