## Overview

MICROBE-LIFT Nite-Out II is a concentrated blend of live nitrifying bacteria designed to instantly cycle freshwater and saltwater aquariums. It rapidly reduces toxic ammonia and nitrite levels by establishing a stable biofilter, enabling fish to be added on day one. Safe, reef-friendly, and biodegradable, it supports all aquarium types and helps maintain optimal water quality for healthier, stress-free aquatic life.

## 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.

## Questions & Answers

**Q: so what exactly happens after adding to your tank ?**
A: It puts starter bacteria in your tank which will help with all the bad stuff that can kill your fish {ammonia ,nitrite} I use it every other day on new tanks until i am sure it has matured enough to keep the fish alive.I have been using this for years and still use it on my mature tanks once or twice a month or after I put new water in .{great product}

**Q: When re-adding water to tank do I add micro lift nit out amount according to the amount of water re-adding or according to tank size?**
A: According to tank size This cannot hurt your tank if anything it will help it. This is starter bacteria and I have been using it for years even with my established tanks.

**Q: Should microbe- loft nite- out 11 continue to be added to the fish tank when the ammonia has reached zero concentration?**
A: Make sure you are keeping adding ammonia til its fully cycled. Meaning, you keep adding ammonia until the readings are 0 ammonia, 0 nitrite, and 20-80 nitrate. Then its considered cycled.

This can be continued to be added with water changes to help keep your cycle perfect.

**Q: Is this the same as m/l pl that i use in my koi pond?**
A: No, there are different strains of bacteria. Some stuff in common, such as good nitrifying bacteria, but they're not the same product.

And to the other guy who commented... "Raildawg1," dude, M/L refers to the brand, Microbe Lift. PL is the product name. This person is asking if it's the same as Microbe Lift PL.
