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

I have used all the other products on the market to cycle aquariums and I was just about to give up when someone told me to try this product! Follow the instructions to the T and you will see you should see amonia, nitrates and nitrites change for the better in about 4 days. I would do 50% water changes on my 90 gallon daily to keep the ammonia below 1PPM and treat the water. I switched from a 55 to 90 and lost ALL my beneficial bacteria and have about 25 community fish in the aquarium. This saved my tank and i have not lost one fish yet. In stores this size bottle is REALLY expensive. I have never seen even the smaller bottles go for anything over 14 bucks! Good buy, good savings, great product, if I could give it 6 stars I would! MAKE SURE IF YOU USE TAP WATER AT WATER CHANGES, THAT YOU TREAT YOUR WATER AND WAIT 15 MINUTES BEFORE ADDING THIS PRODUCT OR TURNING OUR FILTER BACK ON! Cheers!

Works well

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.

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!!

It works. I usually do the whole wait 1-3 week deal before even attempting to add fish. But I decided to try this product because I was in a hurry and it works. I fully tore down my tank and re-landscaped the entire aquarium AND made sure my water parameters were within freshwater normal range (GH, KH, pH, ect). I didnt clean the gravel because I wanted to at least keep some of the good bacteria in the tank somehow. I bought two cheap rosy reds within 24 hours of setting up my tank, and theyre still alive but they could be in better shape. The product works but the fish are definitely not 100% happy even if my water parameters are fine. I wouldnt recommend starting a new tank and using this product with delicate/sensitive fish like discus... I will stick to waiting at least 1-3 weeks before adding fish, like I used to. The product works, it just seems a little risky if youre going to buy expensive fish to start a new 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.

This stuff really does work. I had been cycling my 10 gal tank for about 3 weeks when I started it. My tests were just barely showing some nitrite. 8 days later, it was fully cycled. Please note, though, that this won’t work at all if you don’t combine it with an ammonia source. I used Dr. Tim’s pure ammonia to raise my tank to 4-5 ppm for cycling. If you have fish in your tank, that’ll also do it, but fish in cycling is not recommended. I think that some of the negative reviews are from people who thought that this product alone would cycle the tank. It won’t. This adds beneficial bacteria to your tank, but the bacteria will starve without ammonia as a food source. So make sure you have good ammonia levels in the tank before you add this.

Its really quality ... i will buy again

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.

This product stabilized my aquarium very quickly.
