If ammonia and nitrates are 0 and staying there for a week or so with ghost feeding I'd do a big water change to dilute nitrates then add a couple snails and hermits.
If I am honest about it, when I started back up a year and a half ago after 4 years out of the hobby I couldn't keep that patience hat in place no matter what and I did pretty much everything the wrong way and I knew better. I upgraded twice in the first 6 months. Since the final upgrade to the 125 I've been doing it the right way, mostly.
