I did a water test out of curiousity today...

Tank temp: 79' Salinity: 1.024
pH: 8.0 Ammonia: 0.0ppm
Nitrate: 10ppm Nitrite: 0.2ppm

Correct me if I am wrong, but these look very low and w/in tolerable levels. Could this from the water change yesterday?? Or do you think my bacterial colonies are strong and my water movement is good??? It looks like my pH could be higher but, again, this could be my water.
