I recently setup a 40 gallon QT tank. I pulled a decent ammount of filter media from my 150 gallon 4 month old tank and added some bioballs as well. ive been feeding the empty qt tank some flake food everyday but the nitrite just sits at about 20ppm. is it waterchange time for me till it comes down ? or just throw in a cocktail ship and let it rot away ? Im sure this question has been asked and answered quite a few times, but again the search function on this site is less then fantastic.
