  • Multi-cavity plate for simultaneous testing of up to 6 tests at the same time
  • Sensitive to less than 0.5 mg/L
  • Includes reference for test validation
  • Marine or fresh water
  • Range: 0 - 25 mg/L
  • Precision: 0.1 - 1 mg/L & 0.01 - 0.1 mg/L
  • Over 75 tests per box.
Instructions – Normal range1. Fill sample pipette to base of bulb and dispense to a test cavity of the test plate.2. Add one drop of Silicate Reagent 1a and one drop of Silicate Reagent 1b to the sample. Wait 4 minutes.3. Add one drop of Silicate Reagent 2.4. Insert dry stir rod into Silicate Reagent 3 container to coat with a light dusting of powder. Dip stirring rod with Silicate Reagent 3 in test cavity and stir briefly.5. Compare color to color chart after about 1-2 minutes.6. Promptly dispose of completed test solutions by rinsing test cavity under running water. If the test plate becomes stained, soak or clean with a dilute bleach cleaner, then rinse well.
Instructions – Low rangeValues below 2 mg/L can be difficult to discern on the color scale. If you need a more exact number in this range you can run a low range version of the test. Note that this option will consume the equivalent of 6 normal range tests for each low range test done.1. Fill the low range cuvette to within 1 cm (0.5 inches) from the top with sample.2. Add 6 drops of Silicate Reagent 1a and 6 drops of Silicate Reagent 1b. Cap and invert to mix. Wait 4 minutes.3. Add 6 drops of Silicate Reagent 2. Cap and invert to mix.4. Insert dry stir rod into Silicate Reagent 3 container to coat with a light dusting of powder. Dip stirring rod with Silicate Reagent 3 into cuvette and stir briefly. Cap and invert to mix.5. Compare color to color chart after 2-4 minutes. Match color against color scale by viewing from top to bottom (not side to side) against a white background. Divide result by 4 to obtain actual value (e.g. if it looks like 8 mg/L then the actual value is 2 mg/L). Color will have more of a green hue so base comparison more on color intensity and less on exact color hue.
Reference testThe proper performance of this kit may be validated by running a test in the normal manner except that the reference sample is used in place of aquarium sample. It is not necessary to run a reference test to use this kit. The only time you might choose to run a reference test is 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 know the test is giving correct results. To run a reference test, use the Silicate Reference as the sample in a silicate test. Reference value is 6 mg/L.
HintsSample volume is critical; you must use exactly one full stem of sample. Be sure to hold Reagents 1a and 1b vertically when squeezing a drop. Squeeze consistently to ensure a consistent drop size. The goal is for the Reagent 1a and 1b drop sizes to be the same. Using an excess of Reagent 3 in a normal range test will yield a green rather than blue result; do not use an excess, only a light dusting is needed.
InterpretationThis kit is designed to measure from low silicate concentrations (0.2 mg/L) to above natural seawater concentrations. This kit measures soluble silicate and reports it as silicate concentration. To convert to silicon, multiply by 0.3. Natural sea water contains about 10 mg/L as silicate. In reef or other marine aquaria, silicate should be 1 mg/L or less. Silicate is non-toxic to fish and invertebrates, but is ideally kept below 1 mg/L to minimize diatomaceous algae. In freshwater, silicate is not critical. Usually, freshwater silicate concentrations will range in the area of 4–20 mg/L.
Aquarium use only! Keep away from children.
