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

Thank you :)

Great stuff! I use it as reassurance when quick cycling a tank and it hasnt disappointed me yet.

No sirve, no ayuda en nada al agua.

I used it to discernible or noticeable effect.

Works great for new tanks . But dont put sensitive fish or shrimp right away give a chance to work

Works well. Arrived quickly

Great way to start off a new tank.

Where was this 15 years ago? When we first started an aquarium, no one told us about how the water needs to cycle to get the good bacteria established, so we lost a lot of fish. Once we figured that out, it made life easier- this even more so. We have been added it at water changes and I think it has done a lot to keep our tank healthy.

Accurate and much easier to read than a thermometer.

Within 3 days of using the product I started producing nitrates. I had 2ppm ammonia 3 days later .25 nitrite and 5 ppm of nitrates
