D-D RowaPhos Phosphate Remover
D-D RowaPhos Phosphate Remover is a highly effective filtration media designed to remove phosphate and silicate from marine, reef and freshwater aquariums. Controlling phosphate is an important part of maintaining good aquarium water quality, particularly where excessive phosphate is contributing to nuisance algae growth or affecting conditions for corals.
RowaPhos is based on ferric hydroxide and works by binding phosphate from the aquarium water as it passes through the media. Unlike products that simply mask the effects of elevated nutrients, RowaPhos physically binds phosphate so that it can be removed from the aquarium when the exhausted media is replaced.
Effective Aquarium Phosphate Control
Phosphate naturally accumulates in aquariums from fish waste, uneaten food, decaying organic material and other sources. In marine and reef aquariums, maintaining an appropriate phosphate level can be particularly important when keeping corals and trying to control unwanted algae.
RowaPhos provides aquarists with a straightforward way of reducing phosphate and maintaining lower levels over time. It can be used in both freshwater and saltwater aquariums, making it suitable for a wide range of aquarium systems.
Suitable for Media Reactors or Filter Bags
D-D RowaPhos can be used in a suitable fluidised media reactor or placed within a filter bag in an area of good water flow. A reactor generally provides more consistent contact between the aquarium water and the media, allowing RowaPhos to be used efficiently.
When using RowaPhos in a reactor, the flow should be adjusted appropriately rather than allowing the media to tumble aggressively. If using a media bag, position it where aquarium water is forced through the media rather than simply flowing around it.

- Suitable for use in a media reactor or filter bag
- Ferric hydroxide based filtration media
- Available in a choice of sizes to suit different aquarium systems
Using RowaPhos in Reef Aquariums
RowaPhos is particularly popular in reef aquariums where phosphate management forms part of an overall nutrient-control strategy. Maintaining phosphate at an appropriate and stable level can help provide better conditions for corals while reducing the nutrients available to nuisance algae.
Phosphate should still be monitored with a suitable aquarium test kit. Avoid attempting to reduce very high phosphate levels too aggressively, particularly in an established reef aquarium. Gradual, controlled adjustment is generally preferable to creating a sudden change in water chemistry.
When Should RowaPhos Be Replaced?
The working life of RowaPhos depends on the phosphate concentration in the aquarium, the quantity of media used and the amount of phosphate entering the system. Aquariums with initially high phosphate levels may exhaust the media more quickly.
Regular phosphate testing is therefore the best way to determine when replacement is required. If phosphate begins to rise after previously being controlled, this can indicate that the media is becoming exhausted and should be replaced.
Available RowaPhos Sizes
D-D RowaPhos is available in several sizes, allowing you to choose the most suitable quantity for your aquarium and filtration system. Select your required size from the options above.
D-D RowaPhos Phosphate Remover is an excellent choice for aquarists looking for proven, straightforward phosphate control in marine, reef or freshwater aquariums.
