Ok, so when we took down the 265, we kept all the rock in a 55 gallon drum in our office with pumps, a heater and did water changes. The sand had also been cycling in a rubbermaid container with pumps and a heater. All this was added to our 144 half circle. Today we took the water to Aquatek to get it tested and all the levels were great...we were given the go ahead to start adding livestock and corals. So, tonight we added our mated pair of clown fish and their anemone, a yellow tang and a sand sifting starfish.
