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

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.

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!!

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

Foolishly walking through a Walmart fish dept., I made the mistake of checking out their too large stock of forlorn Bettas. One “spoke” to me! I plopped down the $4.97 (or whatever!), for my new finny friend and then made my way to a big box pet store in search of his perfect home. Over $100 later, home we went! So started the saga of setting up an uncycled aquarium. Ammonia problems for weeks, bought the Prime initially, just to damper the ammonia. Then found the Seachem helpline, who held my hand-not REALLY, but almost!-through the next few weeks! They recommended that Stability would likely speed the process by adding the good bacteria. Between phone calls and multiple emails the water finally tested 0ppm for Ammonia yesterday. I can highly recommend the product and ESPECIALLY the members of the support team! Thank you!

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.

I try to do a water change once a week, and add Stability each time in the recommended amount. It really seems to help keep the chemistry stable.

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 ordered seachem prime and seachem stability at the same time to do a fishless cycle. It is now going on 3 months and after dosing with the stability everyday, dosing liquid ammonia when needed up to 3-4ppm( janitorial strength from ACE with no scents or additives), prime when adding new water, a heater bumped up to 84 degrees, having live plants and a few old filters and same baggies of gravel from an established tank I still have NO progress and my Ammonia will not budge. It is completely bewildering. I have a 29g tank and have followed the instructions- I have nearly finished the whole giant bottle of Stability I received with no progress in my cycle at all. I have reached out to customer service with SeaChem and they have not been helpful- they just told me it was because I have 2 sponge filters instead of a hang on the back filter which is total crap- you should be able to cycle a tank with any kind of filter so long as it is the right size for the tank.. ( although they are very nice). I do not recommend this product at all. Maybe I got a bad batch but I am pretty disappointed and really feel like I have wasted my time and money.

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
