RowaPhos 500g

Professional Phosphate & Silicate Remover for Aquariums and Ponds

RowaPhos 500g is the world’s leading phosphate and silicate remover, trusted by aquarists to maintain crystal clear, algae-free water in freshwater, saltwater, reef aquariums, and ponds.

Excess phosphate is one of the biggest causes of nuisance algae and can also disrupt coral health by reducing calcification and inhibiting strontium deposition. RowaPhos combats these issues with its patented ferric hydroxide formula, scientifically proven to be more efficient than any other phosphate remover.

Unlike cheaper alternatives, RowaPhos will not leach phosphate back into the water, providing long-lasting, reliable protection against algae and poor water quality. It is safe, effective, and highly recommended for constant use in reef aquariums where phosphate control is essential for coral growth.
