> 3 dayThis is a very effective BB. I keep it on hand all the time and add it every time I do a water change in our aquariums, which at this time is 5 tanks. Have never had any issues with it. It was recommended by our LFS. Excellent Product.

> 3 dayThe first bottle of this product purchased at a fish store didnt have small white chunks. I also notice this product is set to expire within a few months of purchase. Due to the low price point I chose not to return/exchange them.

Greater than one weekI cant tell if this cycles a tank on its own but it does do something. I think it helps. I got this after I started a tank cycle and then accidentally stalled it and didnt know what to do. My ammonia was being converted to nitrites, so phase 1 was complete, but the nitrites were not being fully converted to nitrates. This lasted months with no change so I definitely stalled it. I figured out a few things I did wrong and I bought this product. As soon as I added this product to the tank, the water would start to look crystal clear. After a while of dosing this as instructed and helping the cycle in other ways, the nitrites were finally converted to nitrates and the tank was cycled.
