Nitrates?

I have a 75 gallon tank that just got done cycling about 2 weeks ago. After the cycle was done I did a 15% water change and tested the water and I have 0 ammonia and nitrites but my nitrates have been staying between 20 and 60ppm. Is this okay for a fish only tank? And I did 3 more 15% water changes after this and it still stays there. I have 75 pounds or more of lr and 75 pounds of ls. Right now there are 2 percula clowns in there and they love the tank.

It's high but since it is fish only it's not that bad. Are you feeding too much? Have you changed your filter media recently? Ideally you would like to be below 20.
