Vinegar won't do a thing...just kinda whacking an elephant in the ass...it won't move.

Thats funny! Ok no vinegar.My params are ng at the moment.As of this morning in the cycle my amonia is zero but nitrites are off the scale...I think I will try scrubbing it off and give that rock a stern warning...and ride it out.
