RowaPhos® – Advanced Phosphate Remover for Reef Aquariums

The trusted solution for controlling phosphate and improving water quality in marine aquariums.

RowaPhos® is a highly effective iron-based phosphate remover designed to rapidly reduce and control phosphate (PO₄) and silicate levels in marine and reef aquariums. By removing excess nutrients before they can fuel nuisance algae, RowaPhos helps create a cleaner, healthier environment for corals, fish, and invertebrates.

Widely regarded as one of the most effective phosphate media available, RowaPhos works safely and efficiently without releasing harmful substances or impacting beneficial bacteria.

Key Benefits for Reefkeepers

• Rapid Phosphate Reduction – Targets and removes dissolved phosphate at very low concentrations.

• Algae Prevention – Helps prevent hair algae, cyanobacteria, and diatom blooms.

• Reef-Safe Formula – Does not release aluminium or harmful by-products.

• Supports Coral Health – Improves colouration and growth by maintaining ultra-low nutrient levels.

• Highly Efficient Media – Small amounts treat large volumes of aquarium water.

How RowaPhos Works

RowaPhos is an adsorptive ferric oxide media that binds phosphate and silicate molecules as water passes over it. Once bound, these nutrients are permanently removed from the water column, helping to stabilise reef chemistry and reduce ongoing nutrient issues.

It can be used in:

• Fluidised media reactors (recommended for best performance)

• Media bags placed in high-flow areas of the sump or filter

Suitable For

• Marine aquariums

• Reef tanks (SPS, LPS, soft corals)

• Fish-only marine systems

• Systems experiencing elevated phosphate or persistent algae problems

Usage & Application Tips

• Rinse gently with RO/DI water before use to remove fine dust

• Start with a reduced dose and increase gradually to avoid rapid nutrient swings

• Replace media once phosphate levels begin to rise again

• Ideal for use alongside protein skimmers and regular water changes

Why Choose RowaPhos?

RowaPhos has become a reefkeeping staple worldwide due to its reliability, effectiveness at very low phosphate levels, and proven track record in demanding SPS systems. It is frequently recommended by professional aquarists and coral farmers for long-term nutrient management.
