Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums 100ml

I assume this worked because I have had no problems. Easy to use and arrived on time.

A great product that can cycle a tank in just a week. Easy to use and saved my tank after a crashed cycle. Make sure to dose Prime and not change the water for a week in between doses!

Worked well

Use it daily when cycling new tanks. Have not lost a fish yet.

I use this when setting up a new aquarium or changing the water out. It establishes a bio-filter and prevents new tank syndrome. It is not a water conditioner to get chlorine and other stuff out of the water. I use a beneficial bacteria from Fluval biological enhancer too when starting up a tank.

Worked well for cycling a ten gallon tank along with pure ammonia from ACE. I simply followed the directions on the bottle. I like stability because you can do water changes with it, as well as use Prime right away.

3 fish-in cycles with no loss of stock. My only caution - follow the directions on the bottle.

Great stuff

It cycled my tank (3 gallon with a betta) in 7 days.

I’ve been using this for a fishless cycle, the process is still going very slow. I’m convinced this product either doesn’t work or I received a bottle that was mishandling, killing the bacteria. EDIT:: I take back what I said, it was my mistake that I was not shaking the bottle. I saw a difference in ammonia within one day when I shook before dosing! Remember to do this because clearly it’s important.
