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

My stepson got a 55 gallon tank for christmas, and I had been trying to get it to cycle for some time before he moved his fish into it, using added ammonia. No luck, so the fish were moved over and we used Seachem Prime (another exellent product) and continuous water changes to keep the ammonia levels down. Two weeks and a couple of bacteria products later, we were still getting 2ppm ammonia and 0 nitrites and nitrates. I ended up getting Stability and the same day the ammonia went down to .25ppm and we finally got readings on the nitrites and nitrates. It has worked very well for us. WORD OF CAUTION: If you get this or any other live bacteria product, make sure you do one day shipping (at least if it is summer or winter). The temperature extremes during average shipping can kill off the bacteria, leading to this being as useful as a bottle of water.

Some people say it allows you to speed up the cycling process even in a complicated reef tank set up... Others say its just snake oil, meaning, it doesnt do anything and you just have to trust it works. My verdict? Ive set up numerous reef tanks, some using this product, some without. Ive also done water changes with and without this product (with, per instructions). Guess what? I have no clue what this does. If it does something, great. If it doesnt, well, at least it didnt make anything worse. So my advice is if you think this will help, it may- and it wont kill anything. If you dont think it will work, it wont. Duh! Its only real if you believe, man. So why 4 stars? I can only assume the guys at Seachem did their research and theyve concluded improvements in the system using the product versus not. Im not a microbiologist, marine biologist, chemist, or alike... Im just a hobbist and enthusiast with a decent noggin. Youre not the fish whisperer, nor am I. Even the tiniest fractional change in water conditions is detected and deeply felt by marine animals. Imagine if earths gravity changed by 0.1 lbs. Imagine if there was a little less oxygen... Youd feel it, youd know, and it would play an epic toll on your body. So remember, whatever it does it doesnt kill your fish. It could be making things better for your tank, or making minor non-painful changes, but until I see death Im not concerned. I can only assume that real scientist developed this solution for a real problem and we should consider using it. Skeptics, shut up unless youve spoken to swimmy the fish. You can never conduct a perfect one to one experiment between using and not using, even if you two identical tanks, water, sand (impossible), rocks (impossible), filters, etc... Every minor difference, even where each tank is resting in the room (slightly different air exposure) makes a difference. Believe, and it works miracles.

Its really quality ... i will buy again

Stability is a great product to help quickly start your cycle. Cycle of a tank goes down to a week unstead if 6-8 weeks. Go slow adding fish still as the cycle is still new. Great product

What’s not to like??

When I first set up my 20 gallon fish tank, Id done a lot of research about the nitrogen cycle. I decided to do a fishless cycle and thought it would take a couple of weeks to finish. I wound up waiting over 60 days, with no nitrates ever showing up. Then I got this stuff. In a matter of days after using according to package directions, the nitrogen cycle finished. When I set up a second tank, I paired this with Tetra SafeStart plus...and the tank cycled in a week! How I wish Id known about this and the value of it before I brought the aquarium home!

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.

Excelente producto

Ive been using this product for a while, its pretty good stuff but you need to take into consideration that the instructions on the bottle are not going to have your tank cycled in 7 days. The way to use Stability is along with Seachem Prime water conditioner, and water changes. You want to dose both of these daily while you fish-in cycle your aquarium. The formula that I have been doing is as follows. If you have less than 1 ppm ammonia or nitrite - dose Stability and Prime, wait 24 hours and check again If you have more than 1 ppm ammonia or nitrite- do atleast 50% water change, sometimes 75% is best depending on how high your ammonia and nitrite is. Then dose Stability and Prime. The key to cycling your tank and keeping your fish healthy is to keep ammonia and nitrite below 1 ppm, by using Prime Water Conditioner because it will bind these into non toxic forms for 24 hours. This also allows your growing bed of bacteria to have something to eat on. I am currently cycling a 20 gallon long tank, with one Oranda Goldfish. They are large waste producers, so I normally double my prime dosage and quadruple my stability dosage just to be on the safe side. Amazon by far has the best price for the 500ml bottles!

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!
