For future reference, you can just combine TT & Prazi if you like. I always dose Prazi at the onset of transfers 2 & 4, or 3 & 5. There are 6 days in-between those transfers, and no need to do a WC before the second treatment since TT does a 100% WC for you. Also, Prazi only remains active for 3 days max, so that part works out too.
The only downsides are if you're dealing with a fish that hasn't eaten yet (Prazi can cause mild appetite suppression), and if you are using an ammonia neutralizer during TT. Some report fish deaths after mixing ammonia neutralizers with Prazi. But I've personally never had a problem.
