Starter Bacteria Aquarium 236 ml - Nite-Out II Safe Start & water Change cycling phase, high-yield cultures, against nitrite, poor values, after medication, fish tank, freshwater, saltwater

Live starter bacteria – ARKA Nite-Out II is a bacteria blend for starting and maintaining freshwater and saltwater aquariums. It supports a stable biofilter base and allows fish to be added quickly. Fast help with ammonia and nitrite – Nite-Out II removes ammonia and nitrite through nitrification with Nitrosomonas and Nitrobacter. This prevents spikes after a restart, water change or new fish. Dosage for tank start – In a new aquarium add 10 ml per 100 litres daily until ammonia and nitrite are no longer measurable. For maintenance add 10 ml per 100 litres once at each water change or new stock. Suitable for freshwater and saltwater – This liquid bacteria blend works in freshwater and saltwater aquariums. For quick nitrification ensure sufficient carbonate hardness and combine with ARKA Special Blend. Practical 236 ml bottle – The 236 ml bottle suits regular use in small to medium-sized aquariums. After opening store at 4–7 °C and switch off UV and ozone for 12–24 hours during use.
