## Description

Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums, 16.9 Fl Oz (Pack of 1)

Review: Stability: A Biofilter Essential - Seachem Stability is a great product, very simple as it is that great nitrifying bacteria that turns fish waste or food from Ammonia to Nitrites and to Nitrates. Ammonia and Nitrites are severely toxic to fish so establishing a tank with this or seeding it with an already established sponge filter is essential to avoid "new tank syndrome" I have been using Seachem products and stability for months but stability and their prime has been staples for every water change to avoid a cycle crash among my API freshwater liquid master test kit. None of their products mess with water clarity, you will see a slight distortion as they settle into the water collumn, although this disperses rather quickly. I highly recommend.
Review: Easy to Use and Works as Intended - This stabilizer has been simple to use and fits smoothly into regular aquarium maintenance. Dosing is clear, and it integrates well when setting up or maintaining a tank. It’s performed consistently with no issues and does exactly what it’s designed to do. The bottle size is practical and should last through multiple uses. Straightforward, reliable, and effective.

## Features

- TANK STABILIZATION: Seachem 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".
- TREATMENT: 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.
- BACTERIA GROWTH: 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 unknown death of an organism), Stability simply becomes more effective.
- USE: Shake Seachem Stability well before use and turn off UV/ozone filter. Use 1 capful (5 mL) for each 40 L (10 US gallons) on the first day with a new aquarium. Then use 1 capful for each 80 L (20 US gallons) daily for 7 days. Fish and other aquatic species may be introduced at any time as long as dosage is maintained for 7 days.

## Questions & Answers

**Q: Safe for live plants and shrimp and snails (freshwater)?**
A: Yes, It is safe. Great products and company! You can e-mail Seachem with any questions and they answer every one! Still not sure just ask Seachem. I use their products and have asked them many questions.

**Q: Do I have to take out my filter when I use this?**
A: No

**Q: Does it have any aloe vera**
A: No. This is not a water conditioning product. This product is supposed to add bacteria to the tank water to prevent new tank syndrome. It works well. Until I started using it I lost a lot of fish. Now I don’t loose fish and have even had multiple fish species breed successfully including angel fish.

**Q: For this product to work, do I have to turn off the UV light (algae control)?**
A: UV (algae light) kill bacteria. Since you are trying to establish “good” bacteria, it makes sense to turn off the UV light when dosing. I dose mine at night when the lights are off in the aquarium. This gives the beneficial bacteria time to establish itself.

### ⭐⭐⭐⭐⭐ Excellent product
*by J***B on November 11, 2025*

Works great! I was having issues with the nitrite being converted to nitrates because of lack of proper bacteria. I followed the 7 day dosage cycle and this completely turned the tank around. It’s stable and fully cycled now.
