In. Very confident in my current setup....we shall see what happens when I set up the new one..haha.
For real though I think what worked for me is that I used new sand rinsed until I hated it. Transferred all the existing stuff except old sand, and started my lights off at 75% less intensity and increased them about 3% every couple days until I got to the place I wanted to be. Other than that I just tried to match the alk, cal, and mag to the old tank. I did not loose a single coral. That was in Feb-march.Have no fear! You sound just like me when we started rainbows army! I went from a 65 g to a 180 g. Transferred everything over about a week or two into the competition. Well rainbows army is still going strong. Good luck
