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

No more no less it works. Cycled my 75 gal with 1 bottle of Stability & a very small amount of filter media from an established tank. Only took a week and a half, two weeks tops.

After attempting to cycle three new tanks using traditional means with no success, I did lots of online research and discovered everyone in the forums and YouTube videos touting this product. At my wits end, I decided to purchase this product and give it a try. I am pleased to say that after less than one week of dosing my three tanks with this product (according to the written instructions, of course) they are all now fully cycled and producing optimal parameters according to my Tetra EasyStrips. I am so happy I discovered this product, which I cannot recommend enough to those of you who are looking to quickly and safely cycle your tanks for a healthy and happy aquatic environment for your marine or freshwater fish.

Id like to mention that I fully anticipated to receive this in mid April, and instead it arrived a month ahead of time and I couldnt be more grateful. My betta fish tank has begun the nitrification cycle with my betta in it, and in order to keep him as safe and comfortable as possible, I needed this product and Im so happy to be able to have it to speed up the process in the safest way possible. I completely trust Seachem with each and every one of their products, and Im so happy to have been able to order it from such a reliable source. Thank you!!

I use this when I do my half water Change. Keeps my fish healthy along side with the chlorine removal

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 couldn’t get my tanks beneficial bacteria to stabilize and the day we added this changed everything! Stability and Prime are all you need!

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!

Easy to use Great for keeping my sons tank super clean Very affordable Will purchase again

Doing research on this product I knew going into it this would be very much a hit or miss outcome. For me, it was a miss, but a mild miss so far. I recently set up a 125 gallon aquarium. On a Sunday I filled it and added the initial dose of Stability. On Wednesday I added a large number of live plants (rooted, non-rooted, stem, and floating) in addition to a school of 10 Harlequin Rasboras. On Friday I did a water test and thought all was well, 0 ppm Ammonia, 0 ppm Nitrite, and 5 ppm Nitrate which is the lowest reading the API liquid test will show. I added a school of 6 Peppered Corys. On Saturday I did the last final dose of Stability, giving a full 7 days of use. By Monday however things went backwards with 0.25 ppm Ammonia, and zero for the rest. Tuesday up to 0.5 ppm Ammonia and again zero on the rest. So for me, this product only worked while I was using it and didnt sustain long afterwards. The directions confirm a theory of mine. I believe it may contain a bacteria that does do the nitrogen cycle, but is not able to reproduce in the aquarium. Thus it establishes at a certain level of ammonia production, and slowly dies off. It is the only way I can explain why the instructions direct the continued use of this product with a monthly dose, and a dose whenever any fish are added. I can see adding a dose with new fish, but the monthly maintenance has to be there for a reason... Without that initial small reading of Nitrates I would of said this product didnt work at all and my live plants are the reason Ammonia has stayed low. Since I do have live plants in this tank (and a lot of them) I cant say definitively that this product worked or didnt work so Im afraid this review may not be all that helpful. I just wanted to share my experience and state that using this product and following the directions, I did not get a cycled aquarium meaning constant 0 ppm Ammonia and Nitrite.
