RowaPhos 5kg

Professional-Grade Phosphate & Silicate Remover for Aquariums and Ponds

RowaPhos 5kg is the ultimate phosphate and silicate removal solution for large freshwater, marine, and reef aquariums, as well as ponds. With its patented ferric hydroxide formula, RowaPhos is scientifically proven to remove more phosphate than any competing product—making it the world’s most effective phosphate remover.

High phosphate levels can fuel nuisance algae, harm fish, and severely disrupt coral calcification by reducing skeletal growth by up to 50%. RowaPhos eliminates this risk by locking phosphate permanently, preventing leaching back into the water even after the media is exhausted.

Trusted by hobbyists and professionals worldwide, RowaPhos 5kg is designed for high-capacity systems that demand consistent, reliable phosphate control.
