Description
Silicate¹⁴+ supplies a reef-safe, bio-available silicate source for marine aquaria. Controlled additions of silicate encourage diatom blooms, which rapidly outcompete nuisance dinoflagellates. Diatoms may leave a temporary brown film on rock and sand; this is expected and will clear naturally once silicates are depleted. Silicate is also a vital nutrient for sponges and other siliceous filter feeders, making Silicate+ a valuable supplement for biodiversity.
Instructions
Diatom Bloom / Dinoflagellate Control: Dose 3 mL per 10 gal (38 L) once daily until a diatom bloom establishes. Expect a temporary brown film; this confirms diatoms are consuming silicate. The tank will clear as silicates are depleted.
Sponge & Filter Feeder Support: Dose 1 mL per 10 gal (38 L) every 2–3 days to maintain ~1 ppm SiO₂.
General Notes: Add to sump or high-flow area. Avoid dosing directly onto livestock, heaters, or pumps. Do not exceed 3 ppm silicate at one time. Test silicate with an aquarium test kit when possible. Each 250 mL bottle treats ~800 gallons at 3 ppm, or ~2,400 gallons at 1 ppm.
