Ask question

Autotrophic nitrate reactor (sulfur nitrate reactor) consisting of a transparent housing fixed on a stable base plate; sulfur granules divided by removable screens; circulation pump with double ceramic bearings for creating a strong circulation current that raises the efficiency and reduces the risk of blockage. An automatic flushing system ensures low maintenance times.

Advantages over other reactors:

high power: best for aquaria with high nitrate input
longe lifetime of the filter material (1 year and longer)
low bacteria growth: less organic pollution in the aquarium
automatic de-aeration
automatic flushing
additional food is not necessary
no costly controler necessary
external or filter sump operation
and of course

Required accessories:

water inlet with enough pressure (bypass from aquarium main pump or extra pump)
if the buffer capacity (KH, alkalinity) is very low, a neutralizing filter can be connected downstream

The built-in circulation pump generates a strong circulation current (upstream), that lowers the danger of blocking and channelling. A higher reaction rate is the consequence. An automatic flushing device ensures regular loosening of the filter bed and reduces maintenance times.

The in-coming water is de-oxygenated by the biological activity of the filter bacteria. If any or low oxygen is in the water the bacteria switch over to nitrate respiration and consume nitrate instead of oxygen; these bacteria obtain the required energy from the sulphur granulate. This de-nitrification process lowers the nitrate concentration of the water.

The out-coming water flows back to the aquarium with less nitrate. The outlet water must not be directed into filters with phosphate adsorbers.

As the sulphur granulate is used up over time, the material has to be refilled every few months. If the capacity of the filter is too high, part of the filter material can be removed from the filter (please store the removed material in a dry place).
