Stability - 100ml / 3.4 fl. oz.

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.

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 Amazon Prime his entire aquarium. Thanks to Seachem, my extensive research (the nitrogen cycle is an important thing to study), and Amazon 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.

Exactly what it describes and really helped Jumpstart my tank

I had some doubts about the product but actually boosted the time to get it cycled so fast, first week the amonia spike went from 4 to 0, the second week, nitrite went from 2 to 0, then finally got the nitrate in the thirs week, definitely recommend if you want to boost your progress, you can cycle with fish inside if the have low amount of waste like guppies but do costant small water changes and use conditioner with detoxifying like prime.

The Seachem stabilizer works great. I made the mistake of rearranging décor in my fish tank.Removing some and adding some new. Doing so , disturbed my beneficial bacteria causing some of my fish to die. Seachem Stability saved what fish I had left. I highly recommend this product. If You're setting up a new fish tank or doing some changes to your old tank.

With no shortage of Biological water treatments available - I've never really relied on them.The reason being is there's really no true shortcut to a fully cycled aquarium - you have to wait and let nature take it's course. In the past I've tried products like Cycle by Nutrafin and Easy start by Tetra but in most cases these products were used in setting up fast quarantine and hospital tanks. Most of these products -want you to use them continuously which doesn't make sense to me.If you have a fully cycled tank why would keep adding new strains of bacteria to already established water? Well, I think because some manufacturers want you too keep coming back for more and the price of admission isn't cheap. Cycle at around $22 for 16 ounces encourages you to dose your tank with 5 ml for every ten gallons once a week - and 10 ml for every ten gallons during water changes. Nonsense. This brings me to "Stability" by Seachem (one of my favorite companies)But being partial to them and their product line doesn't mean I don't question or research as best I can when trying something new.That said, I'm nursing a new 55, a 40 and 125. I had a bottle of Stability which I had bought on a what the heck basis - the 55 has fish in it, I seeded the filter but still had serious ammonia spikes. Seachem claims that the bacteria used in competitive products are inherently unstable. And for the bacteria to survive it must live in the exact temperature, PH and other water parameters in which it was raised and colonized.This makes perfect sense.When you add this bacteria to your aquarium, it survives for a brief while - but then crashes and dies. Stability on the other hand, has bacteria that can survive in almost any kind of water - fresh and salt and virtually any type of water conditions.Seachem states the strain took a decade to develop. What sets it further apart from the competition is that it contains nitrifying and denitrifying bacteria which isn't the case for any other product of it's kind.Seachem also states - other bacterial supplements form toxic hydrogen sulfide - something that can never happen with Stability. With this said, I've dosed the 55 and 40 according to the directions which are 5 ml per 10 gallons on the first dose and a follow up of 5 ml per 20 gallons for 7 days.What I've noticed - and noticed quickly, is that my water is clearly more stabilized. Currently I show no ammonia on the API test or Seachem Ammonia Alert meter - it's been five days since the last dose and all of my readings are in the safe zone. I don't use it for water changes - but having experienced the problems of adding fish to a non or partially cycled tank, I have not so fond memories of daily 50% -80% water changes for weeks..ugh.Where Stability shines is in helping you protect your fish and stabilize the water, especially in keeping the primary fish killer - ammonia in check.So for specific applications Stability is an excellent product. It's harmless to fish and appears to deliver on it's promise. But as a weekly or even monthly addition to established tank maintenance I wouldn't suggest it. To their Credit, Seachem says you can use it as an on going additive - but unlike other products they don't make it sound like you have to.

Stability helped me start and establish a brand new 55G tall from scratch with only one fish departing to the Golden Pond in the Sky (loach swam up the intake into the filter impeller...messy). From day one I did daily testing with the API kit and made an Excel spreadsheet of the data. There were very small, irregular ammonia spikes at the 2nd/3rd week, but not into the "danger" zone and slowly decreased to 0ppm by the end of the 4th week. Nitrites and nitrates increased from the 3rd week and then hovered at a "very acceptable" range below danger zone and then gradually decreased to ~0 ppm for nitrites and ~20ppm for nitrates by the 5th/6th week. The results I got from the test kit were evaluated against a U of Florida's chart (I am a bio major) of Total Ammonia Nitrogen Toxicity (using pH and water temperature as the other parameters), and were in the range that is deemed not dangerous to FW fish for a short term period. With the results of these API test and my personal experience, I would definitely recommend and have been using Seachem Stability as a "jump start" product to establish the important biological filter in a FW aquarium or to boost or supplement the already existing bio filter in an established tank. For those interested about my experience, see below for in depth details. Products used: -Seachem Stability -Seachem Prime -API FW Master Test Kit 1st week: IMPORTANT: FOLLOW THE DIRECTIONS FOR THE FIRST WEEK'S DOSING SCHEDULE BASED ON YOUR TANK'S VOLUME. Added 7 Zebra danios. These are hardy fish and can survive a newbie's foray into fishkeeping and hopefully any mistakes I make. First day: One capful( 5mL) for every 10G of NEW WATER, so 5 capfuls. Days 2-7: One capful for every 20G of water, so ~3 capfuls EVERYDAY. Added 4 black Java loaches/khuli loaches on day 3. Note: Directions says you can add fish/inverts immediately and at any time as long as you follow the all-important dosing schedule above for the FIRST week only. NOTE: After first week, one capful for every 20G once a month, or with each water change, or introducing new fish, or medicating. 2nd week: Added Dwarf gourami and 3 Albino cories. Did 25% water change with Prime, then dosed with 3 capful of Stability, which is the dose for ~60G. 3rd week: Added Bristlenose pleco. Did 25% WC with Prime, then dosed with 3 capful of Stability. 4th week: Added 3 more Albino cories. Added 1teaspoon/10G API Aquarium salt to counter increasing ammonia, nitrites and nitrate spikes. 5th week: Added 5 more loaches. Did 25% WC with Prime, then dosed with 3 capful of Stability. 6th week: Added 2 Amano shrimps. Did 25% WC with Prime, then dosed with 3 capful of Stability. 4 months later: 3 Bamboo shrimps, 2 Amano shrimps, 9 Loaches, 6 Cories, Dwarf gourami, 7 Danios, BN pleco, plants. All fish/inverts growing and healthy. I now only dose 1 capful of Stability with each 25% WC, as my biofilter is now well established and API tests show it doesn't need 3 capfuls for every WC. Thanks Stability!

This is critical: if you use a UV sterilizer, turn it off while using Stability. Stability is a great product and the price is good, too. I've used it to jump start multiple aquariums with ease. I agree with the other reviewer who notes that it does an excellent job with ammonia but isn't quite as potent for dealing with nitrite spikes (hint: nitrite can be super-toxic). The good news is, it does a reasonable job with nitrite and you can pair your dosage with Seachem Prime for additional nitrite detoxification if necessary. Check your nitrite regularly (1-2x daily) while your water is cycling and add Prime with your Stability as necessary. The Prime label claims that up to 5x its normal dosage can be used to detoxify nitrite in an emergency. It works on nitrate, too, but that's not usually a problem for most species. Prime is also a great water conditioner for removing chlorine or chloramine. Recent example (perhaps this will help guide someone new): we have two adult Red Eared Slider turtles in a 75 gallon aquarium. Turtles create a *lot* of waste, much more so than fish. We recently had an issue where most or all of the beneficial bacteria was destroyed (accidentally), and the entire tank began cycling. Basically, it was like starting a new aquarium. We first cleaned out any excess waste in the aquarium, anything that hadn't already been captured by our canister filter. Then we soaked our bio media (Seachem Matrix) in a bucket filled with about 1/2 gallon of tank water and Stability, for a little less than one hour. The chlorine/chloramine in tap water will kill bacteria, so be sure to use water that's already been treated, e.g. aquarium water treated with Seachem Prime. After soaking, we placed the bio media back into our canister filter and performed a partial water change, adding Stability with the fresh water. We then continued to add Stability daily for 7 days, followed by another partial water change. Guess what? Zero ammonia. As messy as two adult turtles eat and with all the waste they make, the nitrite only spiked around 0.25ppm for a couple of days. Short-term this wouldn't hurt our turtles, but could harm fish. Regardless, twice we simply added a double dose of Prime to compensate. In aquariums with lesser load (waste), nitrite may not even be a problem. A good (read: appropriately large) canister filter is key. Also, don't assume you'll be done after 7 days. Keep checking your pH, ammonia, and nitrite until they consistently read zero. We usually don't check nitrate but depending on your species, you may want to research how much nitrate is allowable and check that also. All this to say, Seachem Stability does the job well, even under load. Pair it with Seachem Prime if you are concerned about small nitrite spikes or have exotic species needing extra care. One last thing: one 250mL bottle is good for about 7-days dosage for a 75 gallon aquarium filled to 50-55 gallons, give or take a little. It's also available in other sizes, of course.

i use this all the time and it is great the stablize you fish tank it east to use the instructions are on the side of the bottle but they are tiny so you will need something to make it readable - it does make the water a little cloudy for about 1hr after adding not always but sometimes and there is a smell when you open it and it is quite strong it is easy to use but it is expensive i would say its not value for money its very expensive for what you get and there are other products out there that do the same job - but it does work so this is really up to the individally if they want to pay this or find a cheaper alternative

Used this during a fresh setup and again after a major water change—didn’t lose a single fish. Dosed as directed for 7 days and saw no ammonia or nitrite spikes. Water stayed clear, fish stayed active, and no weird smells or reactions. I’ve used it in both planted and bare-bottom tanks—works well with cichlids, shrimp, and fry. Doesn’t cloud the water, and it mixes clean. Bottle’s compact and easy to stash, and the dosing cap’s accurate enough for small tanks. It’s not magic, but it does what it says—keeps things stable when you’re starting fresh or making big changes. I keep a bottle in the gear stash for emergencies and new builds. 👍 Pros ✅ Fast-acting—supports tank cycling and resets ✅ No clouding—water stays clear ✅ Safe for all fish types and inverts ✅ Compact bottle—easy to store ✅ Works with planted and bare setups 👎 Cons ❌ Needs daily dosing for full effect ❌ No visible change—relies on trust and test kits ❌ Cap can drip—wipe after use ❌ Not a cure-all—still need proper filtration 🧭 Personal Review If you want a bacteria booster that keeps your tank stable without the faff, Seachem Stability earns its spot. I’ve used it across new builds and heavy water changes—no drama, just clean results and peace of mind. Proper stash-ready gear for anyone who wants their tank sorted and stress-free.

Muy buen producto era lo que yo esperaba
