## Overview

Seachem Stability is a 2L liquid aquarium conditioner designed to rapidly establish and maintain a robust biofilter in both freshwater and marine tanks. Its unique blend of aerobic, anaerobic, and facultative bacteria efficiently breaks down harmful waste compounds like ammonia, nitrite, and nitrate, preventing new tank syndrome. Unlike competitors, Stability’s bacteria thrive across a broad range of conditions, ensuring consistent water quality and safety for all aquatic life and plants without risk of overdose.

## Description

From the manufacturer Seachem Stability Stability will rapidly and safely establish the aquarium biofilter in freshwater and marine systems, thereby preventing the #1 cause of fish death: "new tank syndrome". Stability is formulated specifically for the aquarium and contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, nitrite, and nitrate. The bacteria employed by Stability are non-sulfur fixing and will not produce toxic hydrogen sulfide. Stability is completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of over use. The bacteria used in competing products are inherently unstable. The conditions necessary for their growth and development fall into a very narrow range of temperatures, pH, organic loads, etc. When any of these parameters are not strictly within the proper range, the bacterial culture quickly crashes and dies. Stability is not limited this way. The necessary conditions for the growth of Stability's bacteria strains encompass a very broad range. When other bacteria begin to die off (usually from high organic loads caused by the undetected death of an organism), Stability simply becomes more effective.

Review: Good - Good any one can buy if they don't want their fish to die
Review: Highly recommended - Been using this for my aquarium

## Questions & Answers

**Q: Does this product help with algee problems in a new tank?  Does it cause algee?**
A: no. use for new tank syndrome with prime and ph conditioner.  also with every water change.

**Q: Can i keep in refrigerator eventhough not required?  Thanks!**
A: Its not needed. The bacteria will live even outside the fridge.

**Q: Is this really the 2L bottle? The picture is not correct.**
A: Don’t let the picture fool you. The 2liter bottle looks different but still the same product.

**Q: How long must uv light be shut off when adding this product ?**
A: This is what I got directly from their website. 
A: The UV and/or ozone should be kept off for the 7 days you are dosing if you are cycling or for at least 24 hours if it is for Stability™ additions of new fish or water changes. The reason both should be turned off is because UV and ozone break down and kill bacteria.
