I started my aquarium about four weeks ago. My nitrites are about 10ppm and my nitrates are about 2, and I haven't changed the filter which today it started to backflow. I cleaned the filter a couple of times with the same water from the tank. My question is, how can bring down the nitrites and should I put a new filter? I have 4 gold fish in a 10g tank. And I've been doing 25% water changes every other day.
