Treating phalaenopsis with rot

[Pumpkin92]

Yup! I pretty much came to terms that it's time for it to go...
The third leaf rapidly yellowed and I cut it off. And the other two roots (which weren't really viable) are gone now. The rot did responded to the fungicide, quit spreading and has dried up (so far). I know I should toss it, but I'm gonna let it hang around until the last root dies. I don't have many plants so keeping it quarantined is no problem, plus I have some free time.

Thank you all for your great advice! It will save my other phals, believe me...
