Has anyone ever heard of Fritz Turbo Start, I read so many wonderful things about it, that as soon as I set my tank up, I waited 3 days and then went out and got some. It is just now on the public market, and is a small bottle of bacteria that sells for $28, It will completely cycle your tank in a week. It has been three days and testing is normal, on the 7th day I will let everyone know. I have a 55 gallon fish only tank with artificial corals and rock. I plan to add two percula clowns on the 7th day.
