Featuring a synergistic blend of aerobic, anaerobic, and facultative bacteria, it prevents new tank syndrome by breaking down ammonia and nitrites without producing toxic hydrogen sulfide. Completely safe for all aquatic life and plants, Stability supports smoother cycling and healthier aquatic environments with easy daily dosing. ## Description Stability will rapidly and safely establish the aquarium bio filter 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, 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 overuse. Stability is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management. New Tank Stabilization System Rapid & Safe Establishment of Bio-Filter Prevent New Tank Syndrome Freshwater & Marine Review: it’s been part of my tank-start routine ever since I started aquascaping 0 years ago - When I set up a small quarantine tank last year, I underestimated how quickly ammonia can spike in a fresh system. Within a day, I was staring at test kit colors I didn’t like. That’s when I reached for Seachem Stability, and it’s been part of my tank-start routine ever since. 🧪 Cycling Support Stability is designed to introduce beneficial bacteria that help break down ammonia and nitrite. In my experience, it noticeably smoothed out parameter swings during the first week of a new setup. It’s not instant magic, but it definitely supports the biological filter getting established faster than doing nothing. 🌊 Water Stability What I appreciate most is how it helps reduce that “new tank unpredictability.” When dosing as directed, ammonia and nitrite levels tended to stabilize more quickly, especially when I was cautious with feeding. It gave me a bit more confidence during those early days. 🐟 Livestock Safety I’ve used it with both freshwater fish and planted setups without seeing stress reactions. It’s marketed as safe for fish, plants, and invertebrates, and I haven’t noticed any cloudiness or negative side effects when using the recommended amounts. 🧴 Ease of Use Application is simple — shake well and dose according to tank volume. The instructions are clear, and you typically use it daily during the initial cycling period. It doesn’t have a strong smell, and it disperses easily in the water. ⏳ Expectations It’s important to keep realistic expectations: you still need to test water parameters and monitor ammonia, nitrite, and nitrate. Stability supports the process — it doesn’t replace proper cycling practices. Patience and regular testing still matter. 💰 Value for Money Considering how much livestock costs (and how stressful ammonia spikes can be), a bottle of Stability feels like inexpensive insurance for new setups or after major filter cleanings. Review: Keep your tank healthy - I’ve been using Stability for years and very happy with it. The environment of the tank and water quality remains excellent between water changes and maintenance. ## Features - Rapidly And Safely Establishes The Aquarium Bio filter In Freshwater And Marine Systems - Prevents New Tank Syndrome, The Number One Cause Of Fish Death - Contains a synergistic blend of aerobic anaerobic and facultative bacteria which facilitate the breakdown of waste organics - The Bacteria Employed By Stability Are Consulter Fixing And Will Not Produce Toxic Hydrogen Sulfide - Completely Harmless To All Aquatic Organisms As Well As Aquatic Plants Thus There Is No Danger Of Overuse ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002APIJ6 | | ASIN | B0002APIJ6 | | Allergen Information | Yam Free | | Best Sellers Rank | #2,268 in Pet Supplies ( See Top 100 in Pet Supplies ) #10 in Aquarium Water Treatments | | Brand Name | Seachem | | Customer Reviews | 4.8 4.8 out of 5 stars (13,214) | | Date First Available | June 20, 2004 | | Department | Unisex-Adult | | Global Trade Identification Number | 00000116012508 | | Included Components | water treatment | | Is Discontinued By Manufacturer | No | | Item Form | Stick | | Item Type Name | Aquarium Conditioner | | Item model number | 001062 | | Liquid Volume | 100 Milliliters | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 075179 | | Manufacturer recommended age | 1 month and up | | Model Number | 001062 | | Pet Type | Fish | | Target Species | Fish | | UPC | 000116012508 000116008211 | | Unit Count | 100 Milliliters | ## Product Details - **Brand:** Seachem - **Item Form:** Stick - **Liquid Volume:** 100 Milliliters - **Manufacturer:** Seachem Laboratories, Inc. - **Pet Type:** Fish ## Images ![Stability, 100 mL / 3.4 fl. oz. - Image 1](https://m.media-amazon.com/images/I/61ZbydYYM3L.jpg) ![Stability, 100 mL / 3.4 fl. oz. - Image 2](https://m.media-amazon.com/images/I/81QC8j3LH-L.jpg) ![Stability, 100 mL / 3.4 fl. oz. - Image 3](https://m.media-amazon.com/images/I/813rQmqtxJL.jpg) ![Stability, 100 mL / 3.4 fl. oz. - Image 4](https://m.media-amazon.com/images/I/81i1kHnDH5L.jpg) ![Stability, 100 mL / 3.4 fl. oz. - Image 5](https://m.media-amazon.com/images/I/81-iRV-SRWL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: How often do I add this to the tank to get it cycled?
