Seachem Stability

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” 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. Unlike competing products, 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 over use. Stability™ is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management.

Stability™ contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, and nitrate

The bacteria used in competing products are inherently unstable. The conditions necessary for their growth and development fall into a very narrow range of temperatures, pH, organic loads, etc. When any of these parameters are not strictly within the proper range, the bacterial culture quickly crashes and dies. Stability® does not contain any of the aforementioned bacteria.

The bacteria strains in Stability® have been in development for over a decade. The necessary conditions for growth of our bacterial strains encompass a very broad range. When other bacteria begin to die off (usually from high organic loads caused by the undetected death of an organism), Stability® simply works harder and grows faster! The strains function in fresh or saltwater. Stability® contains both nitrifying and denitrifying bacteria, a blend found in no other product. Additionally, Stability® contains facultative bacterial strains which are able to adapt to either aerobic or anaerobic conditions. The bacteria in Stability® are non-sulfur fixing, another innovation in the industry. Most other bacterial supplements will form toxic hydrogen sulfide under the proper conditions. Stability® will not, ever.

Features:

  • New tank stabilization system for marine and freshwater
  • Rapidly and safely establishes bio-filter
  • Prevents "New Tank Syndrome"

*** 4L: please allow 48 hours delay ***

Directions:
Use 1 capful (5 mL) for each 40 L (10 gallons*) on the first day with a new aquarium. Then use 1 capful for each 80 L (20 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. For optimum biofilter performance use 1 capful for each 40 L (10 gallons*) once a month or with each water change and whenever introducing new fish or whenever medicating an aquarium.

A: The UV and/or ozone should be kept off for the 7 days you are dosing if you are cycling or for at least 24 hours if it is for Stability™ additions of new fish or water changes. The reason both should be turned off is because UV and ozone break down and kill bacteria.

A: The bacteria should be able to find a suitable home within 24 hours.

A: Yes, Stability™ will prove very helpful in removing ammonia and nitrite, including nitrate, as a result of the increased bioload. If your ammonia level is not at zero, a combination of Stability™ and AmGuard is very useful and great in reducing ammonia toxicity on the bacteria blend as the bacteria consumes the ammonia, nitrite and nitrate in the aquarium

A: The bacteria in Stability™ are alive but not active. They exist in a spore form. They can withstand extreme temperatures and do not require food to survive. When you add them to your aquarium they become active due to dilution.

The bacteria that require refrigeration are active. Refrigerating them slows down their life cycle and they require less food when cold. Because they are active they do require food, and that is packaged with them. They also will not survive extreme heat or cold and will die when they run out of food.

A: It is very hard to overdose Stability. You can really never have too much beneficial bacteria. The worst thing that could happen is a bacterial bloom in the water column, but this is rare and will clear on its own, should it occur.

A: Since every tank will cycle differently, it is difficult for us to give an exact time frame as to when your tank will be fully cycled. However, generally most tanks are cycled within 4-6 weeks.

A: Yes, for expedited cycling times, you will want to add a pinch of food daily until you have an ammonia reading. At that point, you can stop adding the food and let the bacteria run its course.

Doesn’t look like the pictures
Style: 1 Pack - Dragon with Lantern
Another small joke of an ornament. Doesn’t glow. It’s gray with no coloring and it’s small.

I Just Want to Help People With Skin Problems!
Style: Tolerance Control Soothing Skin Recovery Cream
I so wish I had known about this skincare line a long time ago, but just glad I did find it at all. I have rosacea (including ocular rosacea) diagnosed by a dermatologist. I had been through all the typical stores and websites, trying so many things over the last 15 years. Yes, most were supposed to be for people with skin problems. EVERY SINGLE TIME I tried something, within five minutes, my skin was bright red. My skin reacted to EVERYTHING. I started to believe there was not one single product on the entire planet that my skin would not react to! It was so frustrating. Purchase, fail, repeat. Thing is, I had tried their spring water spray. I sort of ignored all the other products until I was talking to someone randomly and they asked if I had tried Avene. Honestly I decided maybe this was providence and that I had better try it just to be on the safe side. What would life be like if I had ignored their advice and not tried it? If this company ever goes out of business, I will have to live with terrible skin because I already know there is nothing else out there. I had read a review whereby someone said their doctor told them the longer they used the products, the better their skin would get. This is completely true. But even initially, all I cared was that I could relieve the dryness with SOMETHING that did not turn my skin RED IMMEDIATELY! Even THAT, I would have been happy with! Now for the rest of the benefits. I had the good intuition to purchase two of these when they were on sale. I am so glad I did. I use it like crazy every chance I get. It just feels so good going on and I like touching my skin even after the product dissipates. No redness, no irritation, it actually CALMS my skin. And makes it like, well, "real skin." I'm glad I also got the thicker version in the tube, Cicalfate. This is my go-to for dryer areas and in the winter. The two together along with the water spray, if you like to use something like that, are a great overall program. Definitely other things I would like to try. Again, my goal was to help others who have skin problems because everything else out there has no concept whatsoever of calming the skin, but the exact opposite -- irritating it worse (even if those products are supposed to help with redness or irritation). And I felt the company truly deserves a shout-out because they GET IT when it comes to skincare products. Whatever they've done, they are experts, far more than all the other skincare lines and I don't care how long those have been around. If it doesn't immediately tell you your skin "likes it" and shows it by not reacting or immediately getting better, why on earth would you pay your hard-earned money to buy it and keep using it? It's worth every penny, don't bat an eyelash, your skin is worth that and more. If it's on sale, get a lot of it because trust me, you are going to want and need it. You will be so glad you got more than one. I definitely am! THANK YOU, AVENE, WE LOVE YOU HERE IN AMERICA! YOU UNDERSTAND SKINCARE LIKE NO OTHER COMPANY! Update: Wanted to comment that I'm still so grateful for a product that does FAR MORE than what you expect! I recently bought more. I watch my skin calm down the minute I put it on. I don't know entirely how the ingredients do what they do, but to the company ... please don't fix what isn't broken! Too many companies have a good thing and then change it. Please don't, the products are perfect and far beyond expectation! I also wanted to mention it seems the Tolerance tube will get EVERY LAST BIT out, you won't be wondering if there is anything left you are discarding. The Cicalfate tube is a bit different, it's more like a squeeze tube. But I feel I can still get the product out to use it all. That said, you get your money's worth. I'm also starting to use the Cicalfate on my hands in the winter, too (which are sadly starting to show my age). But this product line has literally CHANGED MY LIFE! BUY IT, it's the REAL DEAL!

Love this cream
Style: Tolerance Control Soothing Skin Recovery Cream
I absolutely love the Avène Tolerance Control Soothing Skin Recovery Cream — it’s become a sanctuary for my sensitive skin. From the very first application, I noticed how calming and gentle it feels. The texture is rich yet lightweight, absorbing beautifully without any greasiness. This cream has been a game‑changer for days when my skin feels irritated, reactive, or overwhelmed. It instantly soothes redness and discomfort, and over time my skin feels stronger, more balanced, and resilient. What really stands out is how comfortable and nourished my skin feels all day long — no tightness, no irritation, just pure relief.

Great for Sensitive Skin
Style: Tolerance Control Soothing Skin Recovery Cream
I have very sensitive skin and have tried everything to try and prevent rosacea flairs. I recently came across this brand and I absolutely love this recover cream. I consider this now the holy Grail for Rosacea and sensitive skin. It makes my skin feel hydrated and non-reactive. It is soothing and I just cannot get enough of it. It is pricy but it is worth it to not have my face constantly feeling like its burning or irritated.
