Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums, 16.9 Fl Oz (Pack of 1)

I have read a lot of the reviews of problems people have had, while I dont agree with the claim of instant bio filter as in my 30+ years I have never seen or found any product that will actually create a full, stable cycle, only time and the miracles of nature, I do not believe any cycle that is rushed is stable enough to handle what is thrown at it! I do think Seachem would be wise to change that! There really is no shortcut to a proper cycled tank that could take up to 6 weeks! This stuff is really for the routine maintenance that it is more suited for like filter maintenance or gravel vacs anywhere or anytime you might loose Benifical Bacteria. I only use this during those times on my 90,135 & 220 gallon tanks and have had zero issues others have claimed which tells me there lack of understanding of the nitrogen cycle or what the product can really do! This product will no way cycle your tank it may help but too many factors contribute to a completed cycle. What this will do is help during routine maintenance to replace loss of BB as well as it could aid in any small spikes. I also will not deduct stars for bottles leaking and or damaged as others have done (guess they dont understand product reviews? If Seachem shipped then different story), as that has zero to do with the results of the product

Works well. My fish are happy.

I started using this right before I broke down and moved my tank to a different location in the house. I used about 4 gallons of water from the old tank, new planted substrate (Eco Complete) and some plants. I added this per the instructions and I havent had any spikes in ammonia. I can credit some of that to the old water, reusing the filter media(Aquaclear), the plants, and the live bacteria in the substrate, but I think it helped. Ive also been using it in my smaller tanks and noticed smaller than usual spikes in parameters. A good purchase, and Ill continue to use this and Prime.

I love my fish and was worried because the water was a bit yellow. This product helped stabilize the water.

Ive been using Seachem for years and they have never failed me. Their products are great and the stabilizer definitely does its job well. My fish are alive and healthy!

This stuff really does work. I had been cycling my 10 gal tank for about 3 weeks when I started it. My tests were just barely showing some nitrite. 8 days later, it was fully cycled. Please note, though, that this won’t work at all if you don’t combine it with an ammonia source. I used Dr. Tim’s pure ammonia to raise my tank to 4-5 ppm for cycling. If you have fish in your tank, that’ll also do it, but fish in cycling is not recommended. I think that some of the negative reviews are from people who thought that this product alone would cycle the tank. It won’t. This adds beneficial bacteria to your tank, but the bacteria will starve without ammonia as a food source. So make sure you have good ammonia levels in the tank before you add this.

Pros: -Fast-acting. I rely on it often during emergencies, and its potent. For example, I recently used 3 caps on a terribly neglected 3-gallon tank of water with ammonia readings as high as 8ppm (-In other words, ultimately lethal to most any fish that dont have the ability to draw oxygen from the water surface like bettas and gouramis. And even they will eventually chemically burn their gills by breathing it in, anyway), and 8 hours later the ammonia readings came back at 0ppm. Cons: -Make no mistake; ammonia concentrations over .50ppm WILL kill the beneficial bacteria colony youre trying to estabilish from your bottle of Stability. If you really cant do a full water change and need to use this on an already highly polluted setup, use a generous amount of Seachem Prime to temporarily detoxify said ammonia so that the beneficial bacteria have time to eat it before it kills them. -It is not uncommon for a fresh bottle of Stability to arrive carrying pollution of its own. I would suggest immediately using an ammonia test kit (-Do NOT use tests in the form of strips if youre new to aquarium keeping) on the contents of the bottle. If concentrations are higher than 1ppm you will likely only be adding dead microbes to your tank, and as they decay they will make things even worse for your fish. -Although harmless, large quantities of Stability can cloud your water. If you experience this and it really bothers you, take it as a sign that you need to cut back on the size of your doses. -Although it does have a decent life expectancy, do not assume your Stability will last until the purported use-by date. I would not recommend buying large bottles of it unless you know, for certain, that youll be using it within a few months.

my son told me about this product, he uses it for his 100 gal tank, i use it for my 5 gal tank. easy to use and works great.

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 Floridas 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 WEEKS DOSING SCHEDULE BASED ON YOUR TANKS VOLUME. Added 7 Zebra danios. These are hardy fish and can survive a newbies 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 doesnt need 3 capfuls for every WC. Thanks Stability!

Great buy... use with prime and stress guard
