> 3 dayI use this when starting a new tank and my tanks cycle in 3 days. I also use it when I add fish and when I do a water change. You cant beat it. Great product! I recommend.

> 3 dayThis is a great product. I ran out of it once and used another product that gave off a horrid sulfur smell. This is odorless and my fish do very well. When I used the other product my fish seemed to not like it either but that could have been my imagination I suppose.

03-06-2025This stuff is awesome for beginner freshwater owners! I wasnt sure what to use for my new Chi by Fluval aquarium to keep my fish healthy and water condition stable. Once I started using it my bettas fins started growing longer, brighter and full of color. Highly recommend and the larger bottles have a measuring cup on the top so you know how much to use!
