Stability 250 mL / 8.5 fl. oz.

I used this to help cycle my aquariums along with necessary water changes. Granted I changed 50% of the water the first week everyother day due to going from 5 gallons to 10 to 20 gallon tanks for my fish. Bought the fish before the tank kind of deal. But I used this during those changes and for a week once established in there new tank and the cycle was done by the end of the second week. I used the test strips to test the water. At first I stopped useing it then went back to using it when I do water changes. Somehow it makes a difference even though the tanks are cycled and stay below 20ppm nitrates.

used this to cycle my aquariums. Sped up the process by seeding with beneficial nitrifying bacteria. Only need a capful per 10 gallons.Dosed for about 6 weeks. Had to buy this bigger size as small bottle wasnt enough. Hope this helps.

good price would recommend

Use as directed, and you don't have to season the tank as long. Excellent product!

work great

I can not get this in my home town,,thank you

This is good stuff for a aquarium, I will always use this.

Stability is a great product. I have used this over the course of the last three months cycling a new tank with fish in the tank. It basically just gives your water the bacteria it needs to fight off the toxins that can kill your fish.

One aquarium store recommended using Stability daily, according to directions for tank size, to clear up my problem with cloudy water. I'm doing that, and it helps a lot.

works well for our fish after water changes
