MICROBE-LIFT Nite-Out II Aquarium Bacteria

MICROBE-LIFT Nite-Out II is a blend of live nitrifying bacteria for freshwater and saltwater aquariums, including marine reef tanks. It is used to start a new tank and to keep nitrification steady in an established one. This page covers the 16 Ounces bottle (NITEH16) and the 8 Ounces size (NITEH08).

The bacteria inside

MICROBE-LIFT names the two groups that do the work: Nitrosomonas oxidize ammonia to nitrite, and Nitrobacter oxidize nitrite to nitrate. Both are needed for a working biofilter. Nitrate is far less toxic and is removed by water changes and plants.

Starting a new tank

MICROBE-LIFT suggests adding Nite-Out II before fish or other marine life go in, so bacteria are already present. Whether you add fish early or wait, stock slowly, feed lightly and test ammonia and nitrite every few days with a kit like the API Freshwater Master Test Kit. Raise the stock only when both stay at zero.

Ongoing use

• After big water changes or filter cleaning
• When adding several new fish at once
• After medications that may have disturbed the filter bacteria

Safety

The maker describes the formula as non-toxic, biodegradable and reef safe, suitable for community tanks, planted systems and marine reef aquariums.

Pairing with Special Blend

MICROBE-LIFT pairs Nite-Out II with Special Blend: Nite-Out II handles ammonia and nitrite, while Special Blend breaks down organic sludge. Using both on their weekly schedule covers the two sides of waste processing.

Storage and handling

Live bacteria products last best when kept cool and out of sunlight. Shake before use, and dose after dechlorinating tap water, since chlorine kills bacteria. Turn off UV sterilizers briefly after dosing so the bacteria can settle into the filter.

The 8 ounce bottle is enough for a single small or mid-size tank start-up. The 16 ounce size suits larger aquariums or keepers who dose routinely after maintenance across several tanks.
