Seachem MultiTest Silicate

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.
MultiTest™ Silicate measures silicates to less than 0.5 mg/L in marine or freshwater. This kit measures soluble silicate and reports it as silicate concentration. To convert to silicon, multiply by 0.3. It performs over 75 tests and contains a reference sample for validation.
MultiTest™ Silicate performs over 75 tests
And with the multi-cavity test plate, multiple tests can be run at the same time.
Measures between 0–25 mg/L silicate
Detectable changes on the color chart in 0.1–1 mg/L & 0.01–0.1 mg/L increments
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 Chart
All 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 Plate
All 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.
