Quick Question- Ick Comeback

[fish1031]

If your DT was empty and you put a fish in last monday how long would it take for ick to develop again if it was still in the tank??

There is really no way to answer that, How long did you keep your DT fish free. If you kept your DT totally fish free for at the very least 4 weeks you may be ok. But it is better to keep it fish free for closer to 6 weeks.

it was empty for 30 days

I think you might be pushing it a bit. But time will tell. Just keep a good eye on the situation.
