Cycling finished in a week?

Recommended Posts

Hi, it’s been at least 2 year since I’ve had a saltwater tank so I’m wondering if it’s possible to finish a new tank cycle in a week? I have an Innovative Marine 20g with one clownfish. I setup the tank on Sep 16th 2021, I used instant ocean live nitrifying bacteria. Today Sep 21st I’m reading 0 ammonia and 0 nitrites around 10-20 nitrates. The first picture is one from Sep 21st and the second is from the night before is this possible? And what should I do after, should I do a water change or continue to wait?

Did you start with cured live rock?

 

You shouldn't have put fish in there until you were sure the cycle is complete.

looks cycled to me. and yeah, if there's already a fish in there it's kind of a moot point isn't it?

I had dry live rock that I cured for a week prior to starting the tank, and I was told and have read that it is okay to start with a hardy fish to help start the cycle.
