Seachem PhosNet Bagged – Phosphate & Silicate Remover (50g)
Seachem PhosNet is a premium-grade granular ferric oxide (GFO) designed to rapidly reduce phosphate and silicate levels in aquariums. Its high porosity and surface area allow for superior binding capacity compared to standard GFO products, making it more efficient and longer lasting.
This 50g version comes pre-packed in a fine mesh media bag, making it easy to use in canister filters, sumps, hang-on-back filters, or any high-flow area. PhosNet is ideal for controlling nuisance algae, improving coral health, and maintaining pristine water conditions in both freshwater and marine environments.
