Re: Question - Discus QT medication.
Piperazine is available through "rocky mountain discus" and Al is a great guy. My quarantine procedure is a heavy (double dose) treatment of metro for 3 days with big water changes in between. Give the fish two days or so after that and pull the metro out. Then a three dose treatment of piperazine, every other day for5 days with small water changes before every dose. Always has worked well for me, great preventative measure for discus. Your other option is a combination of metro and prazi at the same time (available in a product called general cure by API). I find piperazine more effective than prazi so that's why I use it.
