Seachem Stability Water Conditioner: 1L Bottle for Aquariums & Fish Tanks

gary lees: i can't atest as to whether it will fully cycle a new tank, but, i can however recomend it for bacterial die off in older tanks with lazy owners like me who forget to hoover their gravel or clean their filters often, as long as you follow the instructions to the letter it will have an old tank back to fully cycled by the end of a week, i recomend the 500ml bottle rather than the 250ml its only a few pounds more but it will last you up to 4 years and its useful when you add new fish.

Annika Schulz: Ich nutze das Produkt für ein Meerwasserquarantänebecken. Es hält die Werte wie versprochen stabil, muss aber recht häufig nachdosiert werden.

G.O.: Fully cycled my 40gal in 9 days. This is my 4th tank setup that was started with Stability. Took a couple of days longer than previous 3 times I've used it, but it did the job nonetheless. Just be patient and you will achieve the desired results. Don't forget to shake the bottle before each dose.

Marlon: The media could not be loaded.  This is an high quality beneficial bacteria, I use it in all my setup, it speeds up the cycle I have a 30 gals and I used it for 7-10 days usually putting fish in the same day or next with no problems at all, this is a must have, high performance. Even use before adding more fish.

Jason: Seachem Stability has been a game-changer for my aquarium! I was struggling with an unstable nitrogen cycle in my freshwater tank, but since I started using Stability, my fish have been happier and healthier than ever.

The formula contains a blend of aerobic, anaerobic, and facultative bacteria that help to establish and maintain a stable biofilter in both freshwater and marine aquariums. I've noticed a significant reduction in ammonia and nitrite levels in my tank, which has led to clearer water and fewer water changes.

One of the things I love most about Stability is that it's safe and effective for all fish and plants. I have a variety of fish in my tank, including some delicate species, and they've all been thriving since I started using this product.

I also appreciate that Seachem Stability is easy to use. You simply add it to your aquarium water daily for a week, then once a week thereafter to maintain a healthy biofilter.

Other Amazon reviewers have also had positive experiences with Seachem Stability. Many have praised its ability to quickly stabilize the nitrogen cycle in their tanks, and its effectiveness in preventing fish loss due to ammonia...

Lou: After changing water every other day during a fish in cycle, I finally got this product. Tank cycled within a week of using this product. FINALLY. Maybe it was fluke timing.... but I attribute it to this.

Kodee: I'm new to the hobby. I had recused a betta with fin rot from Petco. He lived in a 1/2 gallon hospital tank while I proceeded to research everything there was to know about aquariums. I also had time to Amazon Prime his entire aquarium. Thanks to Seachem, my extensive research (the nitrogen cycle is an important thing to study), and Amazon Prime...I now have a fully cycled super healthy aquarium! This stuff worked great.

I have a betta. They have a small bioload. So it took longer to establish my cycle....19 days. If I would of had time I would of done an ammonia fishless cycle prior to purchasing the fish. But I rescued him. And I didn't have that option. Thanks to Seachem Prime he was 100% safe throughout the entire cycle.

Just follow the directions. Use Seachem Prime every 48 hours. And test your water to monitor your progress! Honestly it was a ton of fun for me to watch my progress. I fell in love with the hobby more and more every single day. I'm so glad I found this hobby!

I have the Fluval Spec 5 Gallon. And I did over dose the Stability by a few milliliters during the first week. Warning: This worked but also caused a major biofilm. It freaked me out....
