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 ?sh 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.
