Hey guys. I have a kinda stupid question for ya. When is your tank officially considered cycled? Is it when the ammonia and nitrite levels are at 0 and the nitrate levels are moderate? My 40 gallon tank has been up for a week now and the ammonia has lowered to below .25. What would the optimum levels be and how long should it take to get there? I am in the process of a fish-in cycle with 4 platies and two mollies. Will they be okay? I don't want any casualties.
