## Overview

MICROBE-LIFT Nite-Out II is a powerful, concentrated blend of live nitrifying bacteria designed to instantly cycle freshwater and saltwater aquariums. It rapidly reduces toxic ammonia and nitrite levels, enabling fish to be added on day one while maintaining a stable, healthy aquatic environment. Safe for all marine life, reef-friendly, and biodegradable, it supports smooth fish introductions and ongoing tank stability, making it an essential tool for both new setups and established aquariums.

## 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.

Review: Very useful to have - The lid to this product is hard to open but it is still definitely worth it, really benefits aquarium and I'm glad I found this product, one of the most helpful of all the fish products I've bought.
Review: AMAZING, lowers nitrites easily 25-40% over nite at minimum dose - AMAZING, lowers nitrites easily 25-40% over nite at minimum dose By far the best nitrite removing and stabilizing product out there. With 24 hours it will turn your test strip color one whole full color shade lighter and or 1.5 shades within 36 hours. Same with liquid test kits. It’s literally instant cure if you have a an ammonia or nitrite spikes which let’s be honest happens to the best of us!!! I use regularly if I’m Late on a water change or if I change the ecosystem be it plants, new fish or things like decorative items like live rock or heavy polluting fish and especially when fish have live babies or eggs and the fry hatch. That is immediate ammonia spike nitrite spike Get rid of the nitrites and the ammonia will stay far away I usually add with a freshly Rinsed cleaned pre filter / mechanical and then a rinsed charcoal filter. Not new but the previous one just rinse it. If I do I’m my large 180-220-300 gallon tanks with cannister filters I do nothing and let the media work for me You can add extra level Of filter floss to trap the now particles of nitrite if you want but I’ve found doing what I stated above works best Enjoy. Great piece and product to have especially in emergencies or when coming home from a vacation or absence. This fish do crazy things when we’re away lol Enjoy and hope u have the same success I’ve had with this awesome product
