    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.

    It works. Used it to start a brand new fluval edge 12 gal with sand substrate. Water treated with Prime, added a handful of live plants and started the 7 day dosing. On day 2 added a handful of tetras and a couple cories. Add a few more after 7 days. Throughout the 7-day period, and over the 5 months since, I NEVER detected ammonia or nitrites (0ppm) and have seen low nitrates (~10 ppm) using API kits (both test tubes & strips, repeatedly as I had a hard time believing the results). Virtually instant cycling, which I did not think was possible but I now attribute to using this product in conjunction with LIVE PLANTS, which gobble up ammonia and nitrates. Cant stress enough how much better a planted aquarium is for maintaining water quality and healthy fish. Ditch those plastic plants, try a few of the more common aquatic plants until you find ones that do well in your particular setup. Yes its a bit more work --- I follow a regular dosing schedule using Seachem Excel (no CO2 injection) and Seachem Fertilizers (Flourish, Nitrogen, Potassium, Phosphorous) and have beautiful thriving plants and healthy fish (and now shrimp, too)

    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.

    Greater than one week

    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.

    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.

    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.

    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

    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.

    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!!
