  • Seachem Stability Q&A

    I'm a member of a very large aquarist forum ( and we often have the topic of bacteria boosters brought up. That being said, I wanted to give you the opportunity to answer the questions yourself.

    Okay, here goes:

    I know that you cannot reveal the specific types of bacteria in your product, however, it is widely circulated that your product contains "terrestrial" bacteria that drowns or dies off, and also it is claimed that the bacteria in your product actually starve off the actual beneficial bacteria. They evidence this by stating that the directions ask that the consumer re-dose during water changes.

    1. So, is your product a 'non-aquatic' form? Does it drown, or die off in the tank?
    1a. Thanks to BioSpira/TSS marketing, consumers believe that there are only 4 or 5 types of bacteria that are responsible for the nitrogen cycle. So if a product doesn't explicitly claim that it contains nitrobacters, nitrosomonas, nitrospira, etc, then it's passed off as snake oil. Do you have a response to this?

    2. Does it starve off the beneficial bacteria?

    3. Dosing with water changes is recommended, why? The general consensus is that the aerobic bacteria responsible for the nitrifying process is not free floating but rather adheres onto hard surfaces, primarily in the filter area (greatest oxygen content).

    4. Most often in our forum, TSS is recommended over Stability. However, TSS is not readily available at most LFS and ends up being an ordered-in product. I've had mixed results with both TSS and Stability, so I am attempting to stay neutral to both. Your product is readily available at most large LFS, This is a great benefit to the consumer, but do you have anything that can help get people to choose your product over TSS? Any type of hard data or testing that shows Stability's performance?

    There are thousands of people who browse the forum daily so I was hoping for a comprehensive response to post over there to give Stability a voice of its own. Everyone over there promotes and pushes Prime as a water conditioner, so I'm torn to see so much faith in one of your products and little in another.

    Thanks for your time!

    Hello David,

    Thank you so much for your post and for allowing us to answer some of your questions concerning Stability. We appreciate the opportunity to do so, rather than just assuming that it is inferior to other similar products. While youíre correct that the information regarding the types and names of the bacteria used in Stability is proprietary information, I will try and address your questions as specifically as possible.

    1. Please be assured that the strains of bacteria used in Stability are cultured specifically for the purpose of consuming nitrogenous waste to effectively reduce these pollutants present in water. As an aquatics-based company, all of Seachemís products were developed solely for use in an aquatic setting. The notion that only limited species of bacteria, such as nitrobacter, nitrosomonas, and nitrospira are capable of facilitating the nitrogen cycle is simply false; there are numerous other species that are also capable of nitrification and denitrification. Stability contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, nitrite and nitrate. Most denitrifying bacteria are facultative aerobes, which prefer to use oxygen as their terminal electron acceptors, but can also utilize nitrate in an anaerobic environment. The potential for die-off of bacteria does exist with any bacterial supplement; however, providing a suitable biological media, such as Matrix, with plenty of surface area, both internal and external, will minimize any die-off.

    2. Stability does not starve off beneficial bacteria; it contains beneficial bacteria.

    3. Again, providing a sufficient biological media with maximum surface area will minimize the loss of beneficial bacterial colonies during the water change process; but inevitably, there will be some loss when water is changed. Since one cannot overdo it on beneficial bacteria, we recommend adding Stability as a part of oneís routine maintenance simply to replace any potentially lost colonies. Thus our recommendation to dose Stability after changing out water. As a side note, itís not a bad idea to add Stability after treating for a bacterial infection in fish, as inevitably some of the beneficial bacteria will be killed off with the use of antibiotics.

    4. Though to my knowledge, there is no publicly- available data that was compiled by Seachem comparing Stability to other competing bacterial supplements, here are some of the major benefits of using Stabiliity:

    The spore-like form is a characteristic of the bacteria being used and allows us to keep a more viable product for longer. Because of this, there is no need for refrigeration as with competing products, as the bacteria do not become fully active until dosed to the aquarium. This also allows for a longer shelf life (4 years) than one will get with other bacterial supplements. Stability is one of the most, if not the most, concentrated bacterial supplement available on the market. The bacterial concentration in Stability is 26.4 million cfu/mL, that is, colony-forming units/mL. Another one of the benefits of using this product is the environmental tolerance. Because of this environmental tolerance, the bacterial colonies can sustain themselves much more efficiently when exposed to stressful conditions. In these scenarios, the bacteria contained within Stability would certainly out-compete other bacteria that are not quite as enduring.

    Again, thank you for taking the time to pose these questions, and we hope to have given you a more clear picture of how and why Stability works to rapidly establish the biofilter.
