RowaPhos 250g

Premium Phosphate & Silicate Remover for Freshwater & Marine Aquariums

RowaPhos 250g is the professional solution for removing phosphates and silicates in freshwater, marine, reef aquariums, and ponds. Developed in Germany with a patented ferric hydroxide formula, RowaPhos is recognised as the most effective phosphate remover in the world.

Excess phosphate fuels nuisance algae, disrupts water quality, and severely reduces coral calcification. With its exceptional absorption capacity, RowaPhos locks away phosphate without leaching it back, ensuring clear, healthy, and stable aquarium water.
