ROWA®phos—
for reliable, effective removal of phosphate from freshwater & saltwater.

ROWAphos is the most effective phosphate remover on the market today. It is widely used in Europe and is now finding success in the United States. ROWAphos was developed in Germany to reduce Phosphates in the Main Water Supply. It is being used in lakes and ponds and has been refined for the Aquarium Market. ROWAphos will not only remove phosphates but will never release them back into the system.

It has the largest absorption ability of any phosphate product in the market today. This saves the need for immediate removal once the media is full. The product is easy to use and will improve the water quality wherever Phosphate or Silicate is a problem. It is of interest to Marine and Reef Aquariums where its unrivalled capabilities have shown it to be extremely beneficial in the control of nuisance algae’s and the growth of hard corals. Unlike other phosphate removal products, it does not shock the animals or cause problems when used regularly. In fact constant use of the product is recommended, as its abilities to control nuisance algae is a major benefit.

Why is a phosphate removal system necessary?

Phosphate (PO4) in the aquarium is caused by the decomposition of organic substances. Especially in the confined habitat of an aquarium, several of these decomposition processes are caused from food surplus, dead plant and animal matter, and excretions (animal waste, etc.)

It is very important to maintain PO4 concentrations at very low levels which are in harmony with the aquarium's life and habitat. Natural waters that have not been negatively affected by human use typically show very low PO4 concentrations. However, it is nearly impossible to maintain this ideal condition in an aquarium without an artificial phosphate removal system.

An increase in PO4 concentration leads to unwanted growths of nuisance algae, and to the inhibition of lime synthesis in certain specialized marine organisms in saltwater, such as calcareous algae and stone hard corals.

What are ideal phosphate levels for freshwater and saltwater aquariums?

To correct phosphate-induced problems, it is recommended to always keep the concentration of phosphate less than or equal to 0.1 - 0.3 ppm in freshwater aquarium systems (expressed as phosphorus P.)

In saltwater aquarium systems, phospate levels should always be kept below 0.015 ppm (expressed as phosphourus P.)

How is ROWA®phos used to maintain ideal phosphate levels?

The phosphate targets mentioned above can be easily reached with ROWA®phos, which effectively binds PO4 without negatively influencing the water in your tank. With ROWAphos, release of potentially toxic substances like aluminium will NOT occur. When exhausted, the product does NOT release phosphate back into the water. ROWAphos should be used regularly, especially in aquaria with very sensitive fish (discus, for example) and in reef aquariums with complex living systems.

ROWA®phos can either be used in a canister filter as a separate slow phosphate filter, or, alternately, it can function at the end of the main filter system as the final stage, after the biological and mechanical filters. The material can either be used in the filter net supplied with the pack, or sandwiched between two layers of fine filter wool (on the incoming and outgoing flow.)

Please refer to the table below to determine how much ROWA®phos should be used in your system to reduce phosphate in the water column by approximately 3ppm phosphate (measured as PO4-) and to maintain the required low levels on an ongoing basis. The amount of ROWAphos required is determined by both the level of phosphate in the water and the level of phosphate in the rocks, gravel and other substrates within the aquarium.

On new or established aquariums where the phosphate levels are high, first measure the level in the water and assume that 2-4 times that amount may be bound up in the substrate; then adjust the ROWAphos amount accordingly.

The lifetime of the filter material, like the usage, depends entirely on the PO4- concentration in the aquarium. Regular control checks with a precise and reliable phosphate test will show the extraordinary effectiveness of ROWAphos. In addition, it can indicate in advance when the filter material needs to be exchanged.

ROWA®phos can work for several months in the aquarium before replacement is necessary, depending on the initial phosphate concentration and level of feeding. It is important to remember that with an established aquarium that has not used ROWAphos before, phosphate concentrations may be at exceptionally high levels of 5ppm or more, requiring several treatments over a period of time (as specified above for the tank size) to remove the phosphate from the water column and to eradicate the levels previously absorbed into the substrate and rocks.
