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

I was starting a new tank and did some research on how to get through the first cycle faster/easier, so I found this. I started a 20g fresh water,heavily planted tank, and threw this in along with seachem Prime. I let the water sit for 1 day, then went and got 9 neons and some more plants. dosed with Stability daily through the first month. Never lost 1 fish. I tested weekly and everything was staying A-OK, so on the second week, which is when it would normally be most dangerous - I even went and got some shrimp because i felt like the water was safe. So it has been 1 month and I never lost anything and tank is thriving. Plants are growing (thanks to plant lights and co2) Not sure if i can attribute this 100% to Stability - but I would do it the same way again and I would not start a tank without it now. Im continuing to dose with it daily for now.

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

Im sure Seachem Stability works well to stabilize and maintain a biofilter as its advertised, but dont believe the hype that it will instantly cycle your biofilter. Sure, it can help get things off the ground by seeding the filter media with bacteria, but dont expect a colony of nitrifying bacteria in 24 hours or something ridiculous. When used with Seachem Prime you could probably reasonably perform a fish-in cycle in 7-10 days, but Im in the camp that believes a fishless cycle with ammonium chloride and live plants is ideal. Having said that I found significantly better results using Fritz TurboStart 700 to kick off my nitrogen cycle. Stability didnt get me any results after a week using their recommended loading dose and maintenance dose. Im somewhat certain it actually gave me a surface biofilm that Ive never experienced before when using it to start a nitrogen cycle. Once the cycle has kicked off, Ive diligently used Stability to maintain my biofilter by adding it with water changes and stocking new animals. Its never given me problems, but its honestly difficult to gauge how well it performs as theres no water test that can be done to see what kind of impact it makes to an already established tank. I suppose if you have a catastrophic crash in your biofilter or perhaps overload it you could measure its before-and-after performance with ammonia and nitrite tests, but thankfully I havent experienced anything like that. Ill continue to use Stability, Prime, and Pristine in maintenance doses as suggested because as far as I know, its working as intended, and making changes to a stable environment is a recipe for disaster. I just havent had luck with it kick-starting the nitrogen cycle. For that Id put my faith in Fritz TurboStart (or FritzZyme)

I used this to help cycle a new tank, and it worked well. It still took 2-3 weeks to fully cycle. The directions say theres no need to add more stability after seven days, but I kept adding the maintenance dose daily until cycling was complete. Be sure to keep testing your water if you have livestock in the aquarium, and dont just assume all is well after seven days. Do the first heavy dose based on the instructions and your aquarium volume. Then test every day for ammonia, nitrite and nitrate. Ammonia will rise first. Once enough bacteria are eating ammonia, nitrite will start to rise. The next event will be ammonia falling to zero, but nitrite remaining high. Once enough bacteria are eating nitrite, it will fall to zero, and youll start getting nitrate. Once you have zero ammonia, zero nitrite, and start detecting nitrate, your aquarium is cycled. If you have livestock in the aquarium during this process, treat the water daily with Seachem Prime. Ammonia and nitrite are very poisonous. Prime de-toxifies them for livestock, but the bacteria will still eat them, so dont worry about Prime stalling your cycle. Also dose Seachem StressGuard daily until cycling is complete to preserve the fish slime coat. Do a 25-50% water change at least every other day while you have significant ammonia and/or nitrite levels. This will not stall your cycle since most bacteria attach to the filter media and aquarium objects, and it will help reduce the toxins while the bacteria colonies are too small to consume them all. I also use the maintenance dose of stability every time I do a water change, replace/clean filter media, or add livestock. In addition, I add StressGuard and Seachem Pristine, another form of bacteria that helps manage waste removal.

Bought this because I was having trouble cycling my 3 gallon, heated/filtered betta tank (with him in it), and kept getting high ammonia levels, but no nitrites or nitrates, despite frequent partial water changes. And always ending up with cloudy water (despite using a different brand of water conditioner). I also bought Prime. I like how Stability can be used daily, and with Prime. My only complaint is that its hard to figure out exactly how many drops of Stability to use if you have a smaller tank, without doing tons of internet research. I ended up determining that I needed to use only 1.5 ml initially, then .75 ml for 7 days in my case, to help boost the good bacteria my tank needs in order to break down the ammonia. I use a 1ml syringe, but you could also use an eye dropper you can buy at any dollar store. If you use a dropper, a 3 gallon tank would use 10 drops per gallon initially, then 5 drops per gallon daily for 7 days (if youre in the same predicament as me). Then use it monthly or with each water change. Just be sure to shake the bottle well before use, and add the stability to the filter, not the general tank water. Apparently it works better that way, but Prime can be added to clean water changes OR directly to the tank if needed. Our betta seems to be tolerating both products well, and something has kept the ammonia level controlled finally. He seems to be happier now too, so Im happy. Since using both Seachem Prime and Seachem Stability, my tank is clearer than its EVER been, and I dont know which product is helping with that, but its wonderful!!

To clarify this is what you use to start the bacterial cycle in a new fish tank and boost an already established tank. It is used to help break down solid waste in a tank and help prevent bad bacterias from developing. I just started a 55 gallon tank with 10 two year old goldfish and we all know how dirty those fish are... I started my tank with this bio bacteria and it works great. You shake the bottle and you hear some carbonated fizzing from the active bacteria and pour a few caps of this directly into your filters to start the process and it will keep your fish from dieing because of New tank syndrome IE all your fish die a horrible death because of chemical spikes. This stuff works miracles in helping to break down solids quickly and keeping fish healthy. It will make your water milky for a day or so because of a HEALTHY bacterial spike and then it levels out and the balance is found naturally. It is the best thing you can buy for a healthy tank and healthy fish. I can not sing the praises of this enough. Totally hooked on Seachem Stability for life. If you have a 55 gallon tank or bigger buy 2 of the 500ml bottles because I wish I did. I used 1/4 of a bottle in a week starting my tank and its a good idea to put a cap full in your filters after you wash them to get the bio filtration action going again. So over a year you will definitely use up a whole bottle maybe more depending on how much you feel you need it. And if you suffer a disaster and have to do a total water change you need this to keep your fish alive in a non established tank.

My tank would not cycle until I quit using Prime, which makes sense if you think about it. If it ties up the nitrites and nitrates then what are the newly forming bacteria going to consume? It took eight weeks and multiple manufactures of this type of product including this one here to cycle my 75. At the time my tank cycled I was using Foster and Smith bacteria, but Im sure this is a good product and would have worked if I had not used Prime. Maybe my tank was about to cycle when I quit using Prime, I will never know... P.S. I use Prime and Safe on all my cycled tanks

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.

Its really quality ... i will buy again

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.
