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

It not only is boosting my tanks bacteria, but even helped with a bacteria bloom.

it works ok but I havent had the effects like I get with dr tims or ATM colony

Great product already used for years, very good and reliable

I use this product every time I do a water change, the results are good and I am able to keep my tank cycled even without a fish load.

Tried it out on a brand new tank and additionally into a existing tank, I have been having wonderful water quality since then in both tanks. I would recommend a activated carbon filter with this product to take full advantage of the colony

Works great and great price for the 16 oz

I didn’t do a technical test but I set up a lot of aquariums with fish in and sterile-start. I was impressed that shortly later I had an overstocked tank, no casualties, and no nitrogen.

Very small not worth it

Good

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.
