D&D ROWA

Directly to: Rowaphos | Rowacarbon | Rowakalk

Rowa is an innovative brand which invented a range of very useful and effective products for your aquarium. With ROWAphos you can effectively remove phosphate from your aquarium, so you do not have to deal with algae ever again. ROWAcarbon is a high performance activated carbon to ensure you of crystal clear waters. This is applicable to both fresh and salt water aquariums. We strongly recommend to use the Rowa products with a D&D reactor, to be found on this page.

 

ROWAphos

Feeding your fish has always been "feeding your fish and the algae". With ROWAphos that problem is nonexistent. ROWAphos ensures that you will not have to deal with algae in the first place. Phosphate is the primary source of food for algae; ROWAphos will effectively remove this from your aquarium.

We supply ROWAphos in the following volumes
  • 100 ml
  • 250 ml
  • 500 ml
  • 1000 ml
  • 5000 ml
  • MEDIA BAG - pack of 2

ROWAcarbon

ROWAcarbon is an unprecendented high performance activated carbon, based upon the higherst quality of hard coal. ROWAcarbon contains extremely low levels of phosphate, which will ensure a near nonexistent algae growth as a result of the use of ROWAcarbon.

Activated carbon removes all kinds of toxins and yellowing from the water, leaving it crystal clear. Activated carbon also ensures an improved quality of the environment your livestock lives in.

ROWAcarbon has a very low phosphate output index (POI) because of the manner it is being prepared for use. Most activated carbons are washed in phosphoric acids as a final stage, which increases the POI significantly. ROWAcarbon is not being prepared this way, which is one of the reasons why it is the best activated carbon out there.

Features:

  • High performance activated carbon

  • PH balanced

  • Pelleted form

  • Minimal phosphate levels

We supply ROWAcarbon in the following volumes: 

  • 500 ml

  • 1000 ml

  • 5000 ml

  • MEDIA BAG - Pack of 2

ROWAkalk

Kalkwasser or lime water translated from German, is one of the oldest methods of adding calcium to the reef aquarium. It has proven its use: Corals experience a better and stronger growth, without any side-effects.

ROWAkalk consist of 98.2% of pure calcium hydroxide, for making lime water (kalkwasser) and for use in lime water (kalkwasser) stirrers.

Kalkwasser is a solution made by dissolving calcium hydroxide in water. The resultant fresh solution is alkaline with a pH of 12.4 and contains a ready supply of both calcium ions and carbonate ions.

Both these ions are useful within the aquarium: Carbon to buffer pH levels, and calcium for the corals.

Kalkwasser on its own does not contain any other ions that would result in an imbalance within the aquariums water chemistry. Add the kalkwasser with great care: it is highly reactive with CO2, and can alter the pH levels significantly if not used and controlled properly. Please consider the use of a Kalkwasser stirrer.

We supply ROWAkalk in the following volumes:

  • 500 ml
