I have to be honest and my tanks have cycled and been more stable since their 2nd dose of this product. I use it weekly the first month, then once a month with my water changes. This product looks like it has helped my water settle and allowed my plants to grow faster too. I'm honestly impressed at how bacteria works.... if you guys want to know that you're getting the real deal, do this. Take off the blue cap and put a couple of drops of this liquid in it. Close your bottle and let the cap dry up for a day. When you come back, there will be colonies of white matter built up which is the bacteria.... LIVE BACTERIA !!! amazing

It works! I have a divided 10 gallon betta tank. I fought with my tank for months to get my ammonia down below .25, used different products and after 1 dose and 2 weeks later my ammonia was at 0. I will continue to use this with every water change.

Have used Stress Zyme for many, many years now in my tanks. It really does work. Some know-it-alls, claiming with their PHd's, ect. on fish forums, that this is bogus, that there is no live culture bacteria and can't work, that living bacteria cannot be kept alive in a bottle of liquid. Hogwash. Their medicine they take, such as liquid penicillin... is exactly that. Live bacteria in liquid form. In a bottle. Also that penicillin, the fact that it works, proves THIS bacteria also CAN and does work. The over edumacated people need to get educated on their facts and get them straight. Good bacteria culture NEEDS adding to your tanks to make them more like a good natural made spring fed lake or pond system has, good bacteria that 'mother nature' naturally adds. I have an irridescent shark in my tank, have had him/her since 1997. He/she is still healthy, never had any illness that needed treating. Even when I had other fish in the tank with it, this Stress Zyme cultures kept down the smell that a normal tank normally has. I can open the lid and sniff and virtually smell nothing. If I run out, and not use any for a while, the smell comes back, builds up. Start adding Stress Zyme again and the smell goes away. Fish are more alert and calmer with this added. Irridescents are very skittish and splashy fish. If they are calm, and if there is no smell to your tank when using this, then that means this stuff is working. 2 thumbs up.
