as for fish, your tank is still young and probably shouldn't add fish yet
like demonsp said, what are your parameters? you want to shoot for zeros in annomia, nitrate, nitrate
you can do what i did, but it might be soon, what i did was buy 2 clowns during my 4th week of cycle and i QT the clowns for 2 weeks before they went into the tank.
that way i knew my tank was done with the cycle process after 6 weeks
