Hi everyone I am officially the owner of a new TL 550. I also got 6kg of sand and three pieces of live rock (6Kg). The tank is standard and I am an extreme newbie. I was told to put the sand and live rock in with the water which I have done and to run for six weeks? Now which equipment do I leave on and which do I leave off? I have everything off now to help the sand to settle in the water because the visibility is not good. Any suggestions or advice would be greatly appreciated.
