> 24 hourI’ve tried many brands that helps cycle and establish a good bio filter etc. For freshwater, this is the best I’ve used for the money and worth it even if it costs a little more than some of the others.

> 24 hourI 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.

> 24 hourWorked wonders for getting our turtle Brutuss tank to a more self sustaining point after a move. Now I add it just add a bit when water is replaced. Wish there was a Subscribe and save option

> 24 hourMy husband loves it. All the fish stay alive and the tank is clear. Also a lot cheaper buying the big bottle on Amazon than at Walmart or a pet store.

> 24 hourI 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.
