Update: Woke up to severe bleaching of bird's nest coral(see picture). I think it could be STN/RTN (base had been white for a week or so), low salinity (I'll explain below), or the clown goby (%$#%@~!).
Salinity: I replaced my return pump back in May with Aquatop SWP-480 192GPH after failure of the factory pump (it had granulated carbon in it, maybe it's still okay?). This resulted in a water level increase in the tank. This led to a massive salt creep problem. This led (I think to a decrease in the salinity from 1.025 to 1.023).
Fixed it this morning with some plastic hose(see picture). I upped the water change from 0.5L/day to 1L/day and decreased the ATO refill rate from 0.7L/day to 0.2L/day. Will run it like this for 7 days to get an increase from 0.31 to 0.34ppt using 0.35ppt new salt water.
Water parameters are here.
Lights look awefully bright. Birdsnest and most stoney coral do best under heavy blue (75% blue, 20% white) and moderate water flow and salinity at 1.026
