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.
