I cycled in 19 days. I love Seachem. I wont use anything else for my aquarium.
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. You will cloud a little bit at first. And develop a biofilm. You probably wont develop as sever of a biofilm if you have good surface movement. Since I have a betta, who prefers calm waters, I had to baffle the outflow nozzle to slow it down. This slowed surface movement combined with the extra dosage of Stability created the biofilm. However, as soon as your filter starts growing bacteria that film starts just disappearing on its own. Took about a week to fully clear. It was about 10 days before the water really cleared up and the film was gone. My cycle took 19 days. Betta's have a small bioload. This was a major contributor to the extended duration of my cycle....if I had a higher bioload it wouldn't of taken 19 days. If I had done a fishless cycle with ammonia it would of been super quick. About 12 days into the cycle I added a mystery snail. They have huge bioloads compared to bettas. So of course I dosed stability for 3 days. To grow additional bacteria in my biofilter. This also extended my cycle. Everything happened just as I expected it to. And I am a newbie. 100% newbie. Now that I am cycled I will continue to add the recommended dose during weekly water changes. I don’t think this would be necessary if you maintain the health of the aquarium. But it won’t hurt and is a good idea. I will also add this for a few days if I add any new inhabitants to compensate quicker for the increased bioload. Seachem is an amazing company. Their products are the clear favorite among hobbyists. And their customer service is amazing!!! Just head over to their site and send them an email. Or sign up for their forums. Or just go to google and search...chances are there is a fish forum somewhere with a user asking about the same thing you're wanting to know. This product is in spore form. It does not need refrigeration. Nor do you have to worry about high temps during shipping. Obviously you don't want it to be subjected to the elements more than it needs to be. But I know some brands are notorious for 'going bad' in the shipping process. RESEARCH! Buy this. And have a great time with your aquarium!! This is a great product. Just do not forget to test your water. Most use the API Master kits.

Works really well
Has been working really well for the startup of my tank. Doesn't really have a smell and is the perfect size bottle for my 3-gallon aquarium. I feel safe using this product and my water quality has been really good since using it.

Seachem Stability: A Game-Changer for My Aquarium!
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 and nitrite poisoning. Some have even noted an improvement in the growth and coloration of their plants. Overall, I highly recommend Seachem Stability for anyone struggling with an unstable nitrogen cycle in their aquarium. It's a safe, effective, and easy-to-use product that has made a big difference in the health and happiness of my fish.

Great product. I always use this brand in my aquarium. Doesn't hurt the fish while cycling the tank .

Use stability alongside seachem prime and you can add fish the same day. I've done this on many occasion and never lost a fish, and also no stress on the fish, I dose both prime and stability for 7 days
