thanks for the compiments guys! So the tank has been running nicely for about a week now without any problems. Ive been doing water tests everyday to make sure the water parameters are ok and everything has checked in perfect. Until today...I did my usual water tests (ammonia, nitrites, nitrates and ph) everything was good today except the nitrates. 2 days ago the nitrates were at about 10-12 ppm. Now today they are at 0?? Any idea why the nitrates would drop off like that?
