> 3 dayThis 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!

> 3 dayThe product might be good normally. But currently, March 2016, they are shipping a product that is almost two years past its expiration date.

Greater than one weekCant 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.
