What one dose does
PARAMETER
1 ml / 100 L
Silicate
+3.961 ppm SiO₂
Alkalinity
+0.1111 dKH
To raise silicate by 0.2 ppm SiO₂ in 100 L: 0.05 ml.
How it’s used
Composition varies widely by grade (SiO2 ~25-37%, SiO2:Na2O ratio 2.0-3.3, density 1.3-1.6). Use the supplier's spec sheet values; numbers here assume a common 3.22-ratio 'N' grade. Egg-preserving/craft waterglass may be diluted.
Cautions
• Far more concentrated than it looks: 1 ml in 100 L ~ +4 ppm SiO2. Dilute (e.g., 1:100) before dosing.
• Same diatom-bloom and unit (SiO2 vs Si) cautions as metasilicate.
• Caustic; dries to glass on surfaces.
pH effect: raises (very alkaline, pH ~11-12).
