## Summary description

sera Silicate-Test (SiO3) is a water test reagent for measuring silicate (SiO3) concentrations. Supplied in a 0.015 L hanging box, this reagent is intended for aquarium and water-quality monitoring to detect silicate levels that affect algae growth and water chemistry. Use with compatible test kits following manufacturer instructions for accurate readings.

## Long description

sera Silicate-Test (SiO3) reagent is designed for simple, reliable measurement of silicate concentrations in freshwater and marine aquaria. Supplied in a 0.015 L hanging box, this reagent is intended for use with compatible sera test kits to help aquarists and water-quality technicians monitor silicate levels that influence diatom growth and overall water chemistry.
Advantages
The reagent provides a straightforward method to detect silicate (SiO3) concentrations with minimal preparation when used in the matching sera test system. Its compact hanging-box packaging is convenient for storage and helps keep the reagent accessible near the aquarium. Regular monitoring with this reagent supports targeted actions to control algae and maintain stable water conditions.
Suitable for
Freshwater aquarium water-quality testing
Marine aquarium silicate monitoring
Routine checks to prevent or diagnose diatom outbreaks
Water-quality control in aquaculture and hobby setups
Key specifications
Analyte measured: silicate (SiO3)
Volume: 0.015 L reagent
Packaging type: hanging box for retail and storage convenience
Intended use: laboratory-style colorimetric testing within compatible test kits
How to use
Follow the instructions supplied with the compatible sera test kit. Typically, add the specified number of reagent drops or measured volume to a prepared water sample, mix gently, and compare the resulting color change to the kit’s reference scale to determine the silicate concentration. Ensure glassware and test vessels are clean and free of contaminants before testing, and perform tests at consistent temperatures for reproducible results.
Usage recommendations
Monitor silicate levels regularly; concentrations above approximately 1 mg/l (ppm) can promote diatom growth and may be treated with a silicate-binding product suitable for fresh and marine water. Store the reagent in a cool, dry place away from direct sunlight and keep the container tightly closed when not in use.
