Description

The cultures of Nite-Out II contain live nitrifiers to eliminate the toxic effects of ammonium/ammonia and nitrite in the aquarium. This biologically reduces the start-up phase of an aquarium to a minimum. In combination with ML/Special Blend, Nite-Out II provides a natural, safe, and fast start-up solution for new aquariums.

The nitrifying bacteria in Nite-Out II include strains of Nitrosomonas, Nitrospira, and Nitrobacter. Nitrosomonas oxidise ammonium/ammonia to nitrite, and Nitrobacter and Nitrospira oxidise nitrite to nitrate.
Recommended for use with all ARKA products.
After opening, the product should be stored in the refrigerator.

Features

  • Quick and safe start-up phase for aquariums
  • Removes ammonium/ammonia and nitrite
  • Prevents failures due to high ammonium/ammonia levels
  • Effective bacterial colonisation in the aquarium through live cultures
  • Contains strains of Nitrosomonas, Nitrospira, and Nitrobacter
  • Contains live cold-water bacteria which are significantly more effective than conventional bacterial preparations
  • No chemicals - works purely biologically
  • Slight sulphur smell

Note

New Formula:
The number of living bacterial cultures in the bottle has been significantly increased. Therefore, the nutrient solution, which produces a slightly sulphurous smell, also had to be increased. The colour is now slightly yellowish to brownish.
After opening, the product should be stored in the refrigerator.

Application

New Aquariums:
Dose one teaspoon (5 ml) per 40 litres every other day until nitrite and ammonium/ammonia levels are acceptable.

Maintenance and Care:
Dose one teaspoon (5 ml) per 40 litres when performing a water change or introducing new animals.

Hello, can I still use the product about 1 1/2 weeks after starting up the tank? Or does it make less sense then? So far I've only used water conditioner and something for the plants.
