How do you know your fish had parasites, you left out what kind and how you came to this conclusion? Also what species fish?
Also how do you know your tank is cycled what are your readings? If you don't have fish then your not providing an ammonia source for the bacteria to live.
If you didn't clean your filter and kept it running throughout this whole process it should have some live bacteria still. Sounds like at least a mini cycle is in order IMO. Need to know your readings to be sure whats actually happening.
