so i just started this new 55 gal tank and i added about 20 lbs of live rock...my dry rock is on its way...any way the past couple of days i have been noticing that my sand looks like it changing colors...what is this i will post a pic when i get home..i just hope it doesnt hurt my tank...my sand started an almost white color that i got from ***** and it was like that for a good few weeks....and maybe a couple of weeks after the introduction of live rock....
