a lot of times it is just your sps growing is why the tips are white. The base and everythign looks fine right?? Also the white tips don't seem to be moving down right? My guess is that your corals are growing.

actually there is no flesh on the tips white skeleton the bases are fine. and still have great polyp extension. i am just wondering since all my levels are on point. maybe have to dose something else. since it looks like the corals obviously are missing something... since phosphates and nitrates are so low to undetectable. almost like an ULNS. i have brightwell amino, and coral color and restore. just not sure if i should use or not
