Fluval Cycle Biological Enhancer, Aquarium Water Treatment, 16.9 Oz., A8351

This 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!

My tank was cycled in a week with this

Doesnt work. Just wait for the tank to cycle on its own.

Finally a fix for my tank. I was looking for something that could lower the alkaline and nitrate.. Well here it is! My tank has been balanced ever since I bought this!

If youre losing you big guppies you have New Tank Syndrome. Follow the directions on Fluval Cycle and completely eliminate your guppy losses.

ok; but not my favorite product

This is my favorite to use and great price

The product might be good normally. But currently, March 2016, they are shipping a product that is almost two years past its expiration date.

Cant get enough of Hagen Fluval products, like their incredible E-Series electronic aquarium heaters. This product is no exception and I really wanted to try it long term along with occasional use of their Biological Cleaner to enhance tank conditions, etc. Whenever I order the Fluval Biological Enhancer, Amazon.com sends Concentrated Biological Booster, not this Biological Enhancer product. This continued to happen after return requests, and, multiple RE-orders. The same thing happened with Kordon type aquarium water conditioner products, REPEATEDLY!! This is totally UNACCEPTABLE, and dangerous to live aquarium fish/pets!! Im forced to purchase important aquarium medications, chemicals, pharmaceuticals, like this tremendous Hagen product, from anywhere but the Amazons warehouses.

works not more to say
