Be very careful adding livestock after using bio-spira. It can give you a false sense that your tank has cycled, however, the addition of livestock will likely cause parameters to decline. Products like bio-spira really do nothing to prepare the tank for long term habbitaion. You still need to take it slow. This is not a hobby to use short cuts.
Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian
