When to do water change after Illness

[Adele]

I have been treating an Anthias for popeye (combination of shelf meds and epsom salt). The fish is about 90% better so was wondering when would be a good time to do a water change to clean out/dilute chemical meds and epsom. I’d hate to have the issue flare back up with the dilution. I know excellent water parameters are what keeps these issues at bay to begin with.
