When I set up my tank I started with 45lbs ls 15 lbs lcc and 45lbs lr then let it cycle. How long will it take for my sand bed to show life. When I first turn on the lights there are some really really small looking worms swiming in a spiral motion until the filter sucks them up but other than that my fish and inverts are the only things moving around. I have some hair algea and some other type living on the rocks. All tests are normal. Thanks all. Oh yeah, 55 gal.
