Iodine/Iodide / 75+ Tests

MultiTest™ Iodine & Iodide

• Catalysis based, sensitive to less than 0.0025 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

Natural seawater (NSW) concentration of iodide is 0.06 mg/L. Ideally, it is advisable to maintain iodide close to NSW concentration. Concentrations above NSW may not be harmful, and, within limits, may even be beneficial, but maintenance at elevated concentrations should be considered experimental.

The innovative MultiTest™ Iodine/Iodide kit offers a quantitative test for this important element of soft and hard coral growth. It measures iodine or iodide to less than 0.005 mg/L. The color scale peaks at 0.10 mg/L. It performs over 75 tests and contains a reference sample for validation.

Phosphate / 75+ Tests

MultiTest™ Phosphate

• Measures inorganic phosphate 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

Phosphate in natural sea water ranges from less than 0.01 mg/L to 0.3 mg/L. For corals in reef aquaria, such phosphates should be 0.2 mg/L or less. Phosphates are non-toxic to fish and most invertebrates, but are ideally kept below 1 mg/L to minimize algae growth. In freshwater, phosphates are not critical and the allowable concentration is dependent on variables such as nitrate, manganese, iron, and vitamin concentrations, as well as the extent of use of live plants.

MultiTest™ Phosphate measures inorganic phosphate to less than 0.05 mg/L, producing a unique easy to read yellow-green-blue color range in marine and freshwater; however, usually, freshwater phosphate concentrations will be beyond the range of this kit, and dilutions of the sample with distilled water will be required. It performs over 75 tests and contains a reference sample for validation.

Iron / 75+ Tests

MultiTest™ Iron

• 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 fish 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.

Marine Basic / 75+ Tests

MultiTest™ Marine Basic

• Combines the Marine pH & Alkalinity, Ammonia, and Nitrite & Nitrate kits
• Multi-cavity plate for simultaneous testing of up to 6 tests at the same time
• Includes reference for test validation

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.

Nitrite/Nitrate / 75+ Tests

MultiTest™ Nitrite/Nitrate

• Measures nitrite to less than 0.1 mg/L and nitrate to less than 0.2 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

Nitrite is toxic and should be undetectable in any well established aquarium. During cycling, it may exceed 20 mg/L. Nitrate is relatively non-toxic, but it is advantageous to control it to under 20 mg/L.

MultiTest™ Nitrite/Nitrate 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 by this kit are expressed as nitrite and nitrate rather than nitrogen (to convert to nitrogen, simply divide by 3.3 and 4.4, respectively). It performs over 75 tests and contains a reference sample for validation.
