No there's one, just different stages.
- The nitrogen starts as waste from the fish as ammonia.
- During a regular cycling process, the first sign that things are taking place is that the ammonia level will spike. (This is the 'first stage', commonly referred to as the ammonia spike.)
- Then, the ammonia processing bacteria grow in sufficient number to deal with that, creating a great deal of nitrite. (This is the 'second stage', commonly referred to as the nitrite spike.)
- Then, a different bacteria grows in sufficient number to deal with the nitrite, creating nitrate. (This is the end of the cycle as we normally deal with it.)
- (There are other bacteria which under the right conditions can convert the nitrate to nitrogen gas which exits the tank on its own, rather than during a water change - Live rock for marine systems usually contain this type of bacteria.)
Does that help? Its one 'cycle', but during the 'cycling process' there are different 'stages'.
The Safe Start product is supposed to have sufficient numbers of BOTH bacteria to deal with the ammonia and nitrite simultaneously. And whatever ammonia is processed by the first group to nitrite is dealt with by the second type and converted to nitrate.
