This is my 2nd saltwater tank I've done , my question is my LR is turning white ! My tank with LR in it has been up and still in process of cycling for 4wks now , my water : nitrate 5.0 , ammonia is 0.60 , salinity 1.024 , temp. 77f , my test result from API reef masters test kit and the LFS test was pretty close to the same as mine . my last tank with LR in it didnt do this , what you guys think ?
