Product description
Product Description Nite-Out II is a specially developed bacterial blend of purely biological ingredients that accelerates and perfects the establishment and upkeep of marine and freshwater aquariums. It ensures optimally functioning nitrification in the aquarium rapidly and lastingly: NH3 ammonia / NH4 ammonium –> NO2 nitrite –> NO3 nitrate. Together with Special Blend, Nite-Out II replaces the “classic” run-in method and ensures that fish can be stocked quickly and safely. It is used at the start of an aquarium and subsequently, typically after major water changes and for new stocking. Directions Follow the safety instructions and instructions for use on the product label.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
