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

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

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.

Have been using this for some time now and detected no changes to stabilizing water or improving tank stability. I still add it just in case - because I have terrible water problems and hope this helps with the water cycle. I notice no difference. Also for those cycling a tank - do NOT cycle with fish in it, a far better way is to use household ammonia instead of fish to start the cycle going. Look online for the exact amounts of ammonia to add each day - and you actually make the ammonia rise and fall multiple times along with the nitrites until your last dose cycles and both ammonia and nitrites are zero. At that point is when you want to do a water change to get rid of the left over nitrates and just generally get the aquarium ready for your fish. Make sure it is just plain ammonia, nothing with a detergent added. No risk to killing your fish or sacrificing cheap fish to cycle the tank - how cruel and stressful to the fish. My tank lost its cycle probably due to adding too many fish at once. but Stability didnt help - 2 months of trying to get it to cycle and its just now producing nitrates - I feel bad for my fish who have had to suffer through this - if you do have fish in your tank make sure you use Prime daily (they say 48 hrs but I did it daily to be safe). When my ammonia reach 8 ppm I purchased AmGuard which very slowly has help lowered my ammonia levels.

I love this product. However, this vendor shipped it without a cap... not even in the box. Just saying. Luckily I have old caps to measure doses. But this is my favorite product for its intended use.

I use this to fishless cycle my tanks. I combine it with Dr. Tims Ammonium Chloride. By doubling or trippling the dosage on both of these, I can fully cycle my tank in 7-12 days and its AWESOME! If you dont know what Im talking about, its very important that you study the Nitrogen Cycle and learn what it does in a fish tank before you buy any fish. I also use it when adding new fish just to make sure my beneficial bacteria colony stays strong and stable. And it really does keep things stable!

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.

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.

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

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 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.
