## Overview

MICROBE-LIFT Nite-Out II is a powerful 16 oz aquarium bacteria starter that rapidly establishes nitrification by converting toxic ammonia to nitrite and then nitrate. Safe for all freshwater and saltwater tanks, it reduces fish stress and loss by maintaining optimal water quality. Its biodegradable, reef-safe formula supports new setups and ongoing maintenance, making it a must-have for professional and hobbyist aquarists alike.

## Description

Jump-start biological filtration with MICROBE-LIFT Nite-Out II, a concentrated blend of live nitrifying aquarium bacteria for freshwater and saltwater fish tanks. This aquarium water conditioner seeds the biofilter with beneficial bacteria that rapidly convert toxic ammonia to nitrite and then to nitrate, helping prevent spikes that stress fish and cause losses. Formulated with Nitrosomonas and Nitrobacter, it establishes and maintains nitrification in new or established systems. Use as an aquarium starter bacteria for new aquariums and as ongoing support after water changes, filter cleanings, medication, or adding new livestock. Safe, biodegradable, and reef-safe, it works with most aquarium water treatments and is suitable for community, planted, and reef setups. Directions: shake well; dose at setup, then daily until ammonia and nitrite read 0 ppm; add weekly or whenever bioload increases to maintain stability. Note: Nite-Out II does not directly remove nitrate; manage nitrate with water changes or the use of Microbe-Lift Special Blend.
