I am starting a new 55 gallon tank and read the cycling for dummies thread which was quite helpful. I went to the local pet store to buy my test kit and they recommended a product called Nutrafin Cycle. Has anyone had any experience with this? Its supposed to speed up the cycling period. I am debating trying this or using straight up ammonia to start the cycle but would like some input before i do anything. As of now all I added to the water was the tap water conditioner and turned my heater all the way up.
