Can't Get Nitrite Down. Overstocked?

    Hello everyone!

    First post, but I've been doing a lot of reading on this forum and what an awesome community. I've completed the fishless cycle two months ago and slowly adding fishes to the tank. Water parameters were good until two weeks ago when I noticed the water was a bit cloudy. Did a test with API master kit and nitrite was at .50 ppm. Ammonia at 0 and nitrate at 20 ppm. I immediately started doing 25%~50% water change every other day and dose with Seachem Prime and Stability. I reduced feeding to once every other day and fishes are all very active.

    It's been two weeks and I can't seem to get the nitrite down. Nitrite hovering around .25~.50 ppm while ammonia remains at 0 ppm and nitrate at 20 ppm. I wonder if my tank is overstocked? Any suggestions?

    Doesn't look overstocked to me. Could be false readings?
