My tank has been up for about 4-5 months now, but I don't plan on getting an anemone for at least another month. I set it up with live rock and sand so I have had 0 ammonia, phosphate, nitrate and nitrite for 3-4 months now. Since I do have quite a few corals around my rockwork I have come down to two choices. Taking all corals off rocks and put on frag racks while a BTA gets situated or (the more likely of the two) find a nice malu and take the few corals in the sand bed up for a week or so while the malu gets situated.
