Sera Silicate Clear Remover 500g

Sera Silicate Clear is a chemical filter media that permanently binds silicates (SiO₃) — a common cause of diatom and brown‑algae outbreaks — from both freshwater and marine aquariums. It comes in a handy filter‑bag ready to drop into a sump or filter chamber, where it quietly works to pull silicates out of the water for up to three months (depending on silicate load and tank size). Just rinse before use, place it in an area with good flow, and let it do the rest. Keeping silicate levels low helps prevent diatom blooms, supports water clarity, and helps maintain a healthier environment for corals, fish, and invertebrates.
