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

I keep my tank’s water pristine - the nitrate never gets past 20ppm. For the last couple years that <20ppm goal required the water changes happen every 6 days. Part of my routine is testing and recording the nitrate level (pH & temperature too) before and after doing the water. A couple months ago I started adding a couple capfuls Stability at water change time since I had an open bottle to finish up with no new tanks to cycle. The before nitrate test started showing reduced ppm, low enough to make a water change unnecessary. I didn’t believe it so I tested again. Got the same low nitrate reading. . Three more days of testing and finally on day 9 I did a water change. . I still wasn’t convinced but the same thing happened again. And again... No change in the fish, nothing different about the feeding. Nitrate staying low for more days. So odd! Then it dawned on me the only thing different is the Stability. It started to kick in after two water changes. It is why the changes are 9-10 days apart now, even for 6 large fancy goldfish in 75 gallons! Thank you SeaChem, the beneficial bacteria in Stability are doing the heavy lifting instead of me!

This product is great, I have used it often and the price was inline and a little lower price than the pet stores

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.

Its the only seachem product aside from prime incan vouch for

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.

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

Its really quality ... i will buy again

When I first set up my 20 gallon fish tank, Id done a lot of research about the nitrogen cycle. I decided to do a fishless cycle and thought it would take a couple of weeks to finish. I wound up waiting over 60 days, with no nitrates ever showing up. Then I got this stuff. In a matter of days after using according to package directions, the nitrogen cycle finished. When I set up a second tank, I paired this with Tetra SafeStart plus...and the tank cycled in a week! How I wish Id known about this and the value of it before I brought the aquarium home!

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!

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)
