Salifert Silicate Profi-Test Kit
Silicate occurs in tap water or purified water when the reverse osmosis or deionising unit is not functioning properly. Silicate can result in diatom bloom and can block some essential trace elements such as vanadium and molybdenum. The Salifert Test kit for silicate is very fast, sensitive and accurate, with two scales: an ultra low scale which is particularly useful for marine water and a high scale which is suitable for freshwater environments. Sufficient for 60 tests.

FAQ
How does this test kit detect silicate levels?
The kit uses a colorimetric reaction that changes color based on silicate concentration. The color change is compared to a reference scale to determine the level.
Can this kit be used for both marine and freshwater systems?
Yes, the kit includes two scales: an ultra low scale for marine water and a high scale for freshwater environments.
Is the test accurate for very low silicate concentrations?
Yes, the ultra low scale is specifically designed for detecting very low silicate levels, making it ideal for marine water testing.

I use this kit regularly to monitor silicate levels in my marine aquarium. The test is quick and easy to perform. The ultra low scale is very helpful for detecting small changes in silicate, which helps prevent diatom blooms. I’ve noticed better water stability since using it consistently.

The kit works well for both freshwater and marine setups. I appreciate the two scales — it’s convenient to switch between them depending on the water type. Results are consistent and reliable, and I’ve been able to catch silicate spikes early.
