## Overview

Tetra SafeStart Aquarium Starter is a 50 ml liquid treatment containing specially bred live nitrifying bacteria that rapidly reduce harmful ammonia and nitrite levels, enabling immediate fish introduction in new or treated freshwater aquariums. It remains effective for up to 12 months at room temperature and works best alongside Tetra AquaSafe to establish a stable, healthy aquatic environment.

## Description

Tetra SafeStart makes it possible to introduce fish immediately after setting up a new aquarium. The mix of live bacteria contained within the product instantly creates a safe and biologically active environment, effectively acting as a fast “aquarium starter”. Tetra SafeStart can prevent “nitrite peaks” which typically occur when a biological balance has not been reached in an aquarium and toxic nitrite can't be broken down fast enough. For healthy fish in all freshwater aquariums.

Review: Helped a new tank reduce nitrite and provided clear stable water - We used this with Seachem Prime, and together they have helped improve the levels in our fish tank. We were struggling with high nitrite following the introduction of new fish into a new tank. Together, these two have provided us with crystal clear, stable water.
