Sera Silicate Si03 Test Kit
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).
