I'm confused = wasn't this tank cycled at one time? But earlier in the thread you mentioned ammonia reading .5 and in this post you say nitrites are .5 which tells me that if it was cycled, it's not any more.

Is this the tank you were over cleaning? Or is there something else going on here? Again, you have so many threads on these tanks that it's difficult to determine which tank is which at this point.
