Sera Silicate-Test (Si03)
Makes it easy to monitor the silicate level in fresh and marine water.
Silicate (SiO3) supports the growth of diatoms in marine and freshwater aquariums. The sera silicate-Test allows monitoring the silicate level reliably and easily.
Silicate levels above 1 mg/l (ppm) should be bound with sera marin silicate clear (fresh and marine water).
