I will assume you have had ammonia and then nitrite spike and both fall back to zero, and nitrates are now showing up. If this is correct, then you can add a few small fish. I don't know the tank size, or the intended fish, but go slow with a few at first, and they should be the more resilient of the intended species. Might have more to say if you tell us the tank size and intended fish.

Use Prime with each water change. Monitor ammonia and n itrite after adding the fish. If either rises, do a partial water change with Prime.

Live plants avoid all this problem, by the way, even something simple like some floating plants. Plants need nitrogen and get it from ammonia/ammonium.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
