Cycle time for fish only. No live rock or sand.

[The Grizz]

Well not sure what your really thinking about here Patrick but this in my experience. I recently I had to set up a small tank to medicate one of my seahorse's, cleaned the tank, made new SW, put a HOB filter with just filter floss in it. Moved the seahorse into it as soon as it was at the lower temp required, there hasn't been a speck of ammonia or nitrates.
