Hello I'm from the planted tank side but enjoy reading the salty side as i also have a strong interest in reef tanks. I had really enjoyed reading your thread until this point. In my opinion what you suggested doing here is very poor form. The reason i think this is poor, you are introducing fish to your tank knowing conditions are not perfect. Ammonia burns the gills and the damage is not reversible. You then return this fish. Now Joe Bloggs might walk in off the street into the same fish store expecting to buy a healthy damsel. That damsel isn't healthy though and may die a little down the line. If you want a fish then keep it. If you don't want it then don't buy it!!!!. I also don't think you understand the cycling process fully. Just because your original ammonia had lowered does not mean you are cycled.
Hope this hasn't caused offence and this was not my intentions. Jus stating my opinion
Ok, at that point in time his tank was beginning to be considered cycled. He was doing an unneeded experiment though. The fish weren't affected in any way because of this.
