Hey guys im having a problem with my nitrites. I added an arowana to my tank about a week ago and now my nitrites r around 4ppm. How can i get this down. This past friday is when i noticed it so i did a 25% wc then and yesterday i did a 10% wc and still the nitrites r staying where they r. any suggestions?
check for ammonia, daily 50% water changes till ammonia and nitrite are zero.
