Seachem MultiTest Silicate is a sensitive aquarium test kit designed to measure soluble silicate in both freshwater and marine aquariums. It is particularly useful in marine and reef systems, where elevated silicate levels can contribute to unwanted diatom algae growth.
The kit measures silicate from 0–25 mg/L and can detect levels below 0.5 mg/L, making it suitable for routine monitoring and troubleshooting. It also includes a reference sample so you can validate the test if required.

Why Test Silicate?
Silicate itself is not considered toxic to fish, but elevated levels can encourage diatom growth, particularly in marine aquariums. Seachem recommends keeping silicate at around 1 mg/L or lower in reef and marine systems to help minimise diatom algae.
