I just recently bought a 100 gal. tank to move my saltwater critters into from a 55 gal. I dont want to stress them too much so what would be the best way of moving everyone. I have 2 tangs, 2 clowns, and 10 damsels, and a bunch of inverts, but Im not too worried about them, they are a little more hardy than my fish. I was thinking of setting it up for a few weeks then acclimating them like I would normally OR fill it a little more than half way with fresh saltwater and using some of my old saltwater to fill it then acc. but that would have to be in one day. I dont know if anyone has done this or knows of a better way, if so then please let me know! Oh and I have well water and someone told me that I may have too much iron in my water, are there specific tests for iron???
