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

My fish thrive when I add this to tank

Love this product..... I started 3 aquariums in 4 days and all went well . Follow the directions and you will have you tank up and running quick

I dont know if it was this or my new filter or both, but this was part of what helped me balance out the ammonia in my tank and I love it! I definitely recommend, especially for anyone needing to do a cycle very quickly.

I used it to discernible or noticeable effect.

I was skeptical about it working as quickly as it states, but I am truly amazed. I just got a 75 gallon tank and wanted to cycle it as quickly as possible. I followed the directions as stated on the bottle for setting up a new tank and amazingly my tank cycled in about 3 days. I tested each day and watched the ammonia and nitrite levels go to zero in 3 days. It did make the water cloudy, but nothing a good water change cant fix. Truly amazing product and I would highly recommend using if you would like to cycle your new tank quickly and easily.

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)

It actually works unlike similar productd.

Bacteria needs to be refrigerated. Almost a majority if not all unrefrigerated bacteria starters do not work. Why? Because of the cultures of bacteria in most of these bottles are usually dead strains. Ive done fish in and fishless cycling with this product and it did nothing to start the cycling process, nor did it do anything to begin converting ammonia into nitrites and then nitrates. Do yourself and favor and just buy Fritz Turbo Start 700 which has ACTUAL viable LIVE bacteria cultures.

Started a 55 gallon aquarium with it. I have good water parameters with the three tiger barbs as the only members, One thing I would stress is to shake well before using. The label gives directions for starting aquariums and when the biological filter is stressed.

Great product
