I was told that once I get 1 lb. of LR per gallon I could take my biowheel off because I am running a Aqua C remora pro. I will have about 1.6 lbs. per gallon I have a 50G and I will have about 80 lbs. Pretty soon. Is this true? Seems logical to me but I am just checking with you guys. He said that my biowheel would just be a little nitrate factory.
