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 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: Works.... never lost a fish or shrimp using this - Magical, never lost a shrimp or fish using this. No cycling, just add water, add this, then add fish a few minutes later. great for impatient people. just follow the instructions and you will be golden. Review: I cycled in 19 days. I love Seachem. I wont use anything else for my aquarium. - I'm new to the hobby. I had recused a betta with fin rot from Petco. He lived in a 1/2 gallon hospital tank while I proceeded to research everything there was to know about aquariums. I also had time to desertcart Prime his entire aquarium. Thanks to Seachem, my extensive research (the nitrogen cycle is an important thing to study), and desertcart Prime...I now have a fully cycled super healthy aquarium! This stuff worked great. I have a betta. They have a small bioload. So it took longer to establish my cycle....19 days. If I would of had time I would of done an ammonia fishless cycle prior to purchasing the fish. But I rescued him. And I didn't have that option. Thanks to Seachem Prime he was 100% safe throughout the entire cycle. Just follow the directions. Use Seachem Prime every 48 hours. And test your water to monitor your progress! Honestly it was a ton of fun for me to watch my progress. I fell in love with the hobby more and more every single day. I'm so glad I found this hobby! I have the Fluval Spec 5 Gallon. And I did over dose the Stability by a few milliliters during the first week. Warning: This worked but also caused a major biofilm. It freaked me out. You will cloud a little bit at first. And develop a biofilm. You probably wont develop as sever of a biofilm if you have good surface movement. Since I have a betta, who prefers calm waters, I had to baffle the outflow nozzle to slow it down. This slowed surface movement combined with the extra dosage of Stability created the biofilm. However, as soon as your filter starts growing bacteria that film starts just disappearing on its own. Took about a week to fully clear. It was about 10 days before the water really cleared up and the film was gone. My cycle took 19 days. Betta's have a small bioload. This was a major contributor to the extended duration of my cycle....if I had a higher bioload it wouldn't of taken 19 days. If I had done a fishless cycle with ammonia it would of been super quick. About 12 days into the cycle I added a mystery snail. They have huge bioloads compared to bettas. So of course I dosed stability for 3 days. To grow additional bacteria in my biofilter. This also extended my cycle. Everything happened just as I expected it to. And I am a newbie. 100% newbie. Now that I am cycled I will continue to add the recommended dose during weekly water changes. I don’t think this would be necessary if you maintain the health of the aquarium. But it won’t hurt and is a good idea. I will also add this for a few days if I add any new inhabitants to compensate quicker for the increased bioload. Seachem is an amazing company. Their products are the clear favorite among hobbyists. And their customer service is amazing!!! Just head over to their site and send them an email. Or sign up for their forums. Or just go to google and search...chances are there is a fish forum somewhere with a user asking about the same thing you're wanting to know. This product is in spore form. It does not need refrigeration. Nor do you have to worry about high temps during shipping. Obviously you don't want it to be subjected to the elements more than it needs to be. But I know some brands are notorious for 'going bad' in the shipping process. RESEARCH! Buy this. And have a great time with your aquarium!! This is a great product. Just do not forget to test your water. Most use the API Master kits. ## Features - 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 | | Allergen Information | Yam Free | | Best Sellers Rank | #2,026 in Pet Supplies ( See Top 100 in Pet Supplies ) #10 in Aquarium Water Treatments | | Brand | Seachem | | Brand Name | Seachem | | Customer Reviews | 4.8 out of 5 stars 20,144 Reviews | | Global Trade Identification Number | 00000116012508 | | Included Components | water treatment | | Item Form | Stick | | Item Type Name | Aquarium Conditioner | | Liquid Volume | 100 ml | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 075179 | | Model Number | 001062 | | Number of Items | 1 | | Pet Type | Fish | | Target Species | Fish | | UPC | 000116012508 000116008211 | | Unit Count | 3.4 Fluid Ounces | ## Product Details - **Brand:** Seachem - **Item Form:** Stick - **Liquid Volume:** 100 ml - **Manufacturer:** Seachem Laboratories, Inc. - **Unit Count:** 3.4 Fluid Ounces ## Images ![Stability - 100ml / 3.4 fl. oz. - Image 1](https://m.media-amazon.com/images/I/61ZbydYYM3L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How often do I add this to the tank to get it cycled?
