D-D RowaPhos

Product details

D-D RowaPhos is a phosphate and silicate adsorbent for aquariums and ponds, designed to help control dissolved nutrients that can drive nuisance algae. In practical aquarium use, it’s added to the filter system to bind phosphate and silicate from the water, supporting clearer water quality and helping reduce the nutrient load in both marine and freshwater setups.

Features:

• Targets phosphate and silicate for nutrient control in aquariums and ponds
• Designed to bind strongly so it does not release the removed phosphate back into the system when exhausted
• High binding capacity helps make the media last longer before it becomes saturated
• Built for simple handling and use in filtration, with minimal space requirements in the filter
• Made for consistent use without influencing pH (no pH swing claims beyond the manufacturer statement)
• Widely used in Europe and applied to aquariums/ponds to help manage algae-related issues

Specifications:

• Origin / development: Developed in Germany (originally aimed at reducing phosphates in the main water supply)
• Primary use: Phosphate and silicate removal via filter media adsorption
• Binding capacity: Removes 12 g of phosphate per kg of media
• Removal reference (freshwater): 100 mL removes 1 ppm phosphate from ~630 gallons; 250 mL from ~1580 gallons; 500 mL from ~3160 gallons
• Removal reference (salt water): 100 mL removes 1 ppm phosphate from ~315 gallons; 250 mL from ~790 gallons; 500 mL from ~1580 gallons
• pH impact: No influence on pH (per manufacturer description)
• Leaching claim: Will not release phosphate back into the water when exhausted (per manufacturer description)
