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

I have had this fish for almost 7 years now, and it has been through so much over the years it’s like span was supposed to be up to 12 years if taken care of it well. Sadly however after adding this product it finally met his match. I woke up today in the morning to see my old friend upside down and dead on the aquarium floor. Please don’t buy this product I was trying to help my fish and make the water in it become healthier but this product ended up killing my fish. Goodbye buddy. ( Picture is graphic if you are a fish lover)

New Tank, seems healthy

It was hard to read the instructions on the package, very small print. I tested my water a day before using this product and one week after. The nitrates in my tank did not change at all. I feel it was a waste of time and money.

Easy to use and measure.

Worked great. Fish are alive and well after using.

Hear me now..., believe me later... you need this now.

I used it to discernible or noticeable effect.

Cycled my tank in a matter if three days! All my Ammonia , nitrite , and nitrate. Were all at 0ppm! This is a nitrifying bacteria (helps kill Ammonia Nitrite and Nitrate) . This is NOT BENEFICIAL. If you want Beneficial (helps clean sludge in filter and tank) get fluval waste control.

Save my bacon when my pond was cycling! Use it regularly now with water changes.

I believe Fluval makes the best cannister and fish filters and I trust this brand and no complaints; I have used this to coat booster the beneficial bacteria along with the plant booster and water conditioner.
