Hey guys, I'm currently doing a fishless cycle and about a week ago I had readings of 0 ammonia, 4 nitrites and 80 nitrates. Is there anything that I have to do ? or do i just sit back and finally let this cycle finish. To be honest I've had this tank running since october, yeah very sad but I was so confused during the cycle when i thought i had read everything on it. Also is it common to have both those readings at once?
