> 3 dayI’ve tried many brands that helps cycle and establish a good bio filter etc. For freshwater, this is the best I’ve used for the money and worth it even if it costs a little more than some of the others.

> 3 dayI am fortunate enough to understand that this is not exactly an immediate fix for an uncycled tank. No fish deaths. However, what this stuff is excellent at is speeding up the cycling process. I tracked my 10gal aquarium parameters until they all held stead at 0ppm Ammonia, 0ppm Nitrite, 5ppm Nitrate for 3 days. It took me 24 days to do so, using the recommended dosage of this fluval bacteria. NOTE: You still need to do water changes when you are cycling a tank. I didnt until the last week and then boom... cycling finished 4 days after I did daily water changes. After that you can do the normal 1 per week. Overall, Excellent product for speeding up a tanks cycling. I believe that I could have done it in 2 weeks instead of 3 had I dont more regular water changes. But, for the love of God, DONT ADD FISH IMMEDIATELY!

> 3 dayAbsolutely great for getting my aquarium cycle going. I microdose after every water change, and my ammonia/nitrate levels have never spiked to a warning level. There are very detailed dosing instructions on the label for start-up/water change/maintenance. Recommend dispersing evenly around the tank, with emphasis on the filter/crevices where the bacteria can harbor and colonize well.

> 3 dayIf setting up a new aquarium this is a must have product. It speeds up the it speeds up the biological environment needed for fish to thrive. I set up a new 65 gallon aquarium and by using FUVEL CYCLE I was able to put fish in the new take within 48 hours. Without this product it would have taken 4 weeks to cycle the aquarium to create the same healthy biological environment for the fish to live in.
