ROWA® phos
The ultimate in phosphate removal for freshwater & saltwater aquariums
RowaPhos is the professional method of removing Phosphate and Silicate in all types of Aquariums and Ponds. It has the largest absorption ability of any phosphate product and will not leach back in to the water. 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.
ROWAphos - for reliable removal of phosphate from fresh and saltwater.
ROWAphos is a completely new filter material to eliminate phosphate, which was developed for the company Weil Industrieanlagen GmbH, Osnabrück. Through its outstanding qualities it has the ability to bind large quantities of phosphate by absorption without negatively influencing the water in the aquarium in any way. 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 take place on food surpluses, dead plant matter, excretions etc.
Admittedly phosphate is an important component of life, but it is harmless only in low concentrations. Natural waters that have not yet been affected by human interference show very low PO4 concentrations. It is nearly impossible to maintain this ideal in an aquarium without artificial aid. A rise in the concentration leads to unwanted algae growth and to the inhibition of lime synthesis in certain specialised organisms in sea water, such as calcareous algae and stoney corals. To evolve these phosphate-induced problems it is recommended to keep the concentration of phosphate always below 0.015 - 0.3 mg/l.
This target can be reached easily with ROWAphos, the highly active filter material, which can be used in fresh water as well as saltwater. In particular neither phosphate nor any other substances are released back into the water after the saturation of the filter material. ROWAphos can even be used in aquaria with very sensitive fish or in marine aquaria with less complex organisms.
ROWAphos can either be placed in a canister as a separate slow phosphate filter or can be utilised at the end of the main filter process as the final unit after a biological and mechanical filter. The material can either be applied in the filter net enclosed in the pack or between two layers of fine filter wool (on the incoming and outgoing flow).
How ROWAphos is used:
100ml ROWAphos for 200 - 400ltr fresh water or for 100 - 200ltr saltwater
250ml ROWAphos for 500 - 1000ltr fresh water or for 250 - 500ltr saltwater
The lifetime of the filter material depends entirely on the PO4 concentration in the aquarium. However, regular controls with a precise and reliable phosphate test will show the extraordinary effectiveness of ROWAphos. In addition this will indicate in advance when the filter material has to be exchanged. Depending on the phosphate concentration ROWAphos can work for up to several months in the aquarium, before a renewal is necessary. It is important to consider that in some aquaria, especially those that have been exposed to high phosphate concentrations for a long time, extremely high amounts of PO4 may have built up in the decorations and ground cover
