## Description

Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums 50 ml

Review: Good for setup or emergencies - This stuff had my nitrates down overnight--I recently switched filters, and even though I left the old filter running beside the new one for two weeks, it still wasn't completely cycled and my tank spiked when I took the old filter out. Put in a capful of this and it was way better the next day so I don't have to shock my shrimp with a huge water change. Whew. Don't forget to shake it up well before pouring it in!
Review: Excellent product - Very good item it works great I use quick a few of the different seachem products and I have no complaints. This product is great.

## 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 bacterial 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 the dosage is maintained for 7 days.
- SAFE: 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 overuse.

If you need to help your water parameters get back to normal and safe for your aquarium, this is definitely a must. Follow directions on bottle and all will be better in a few days. Great to have on hand in case of a tank cycle crash as well.
