At night the SPS polyp extention is off the chart. But during daylight ony the stag horn keeps the good extention. My oregon tort and green slimmer have some extention but nothing compared to at night. The milli isn't too bad either during the day. Growth is good on all, especially the stag, but what to do to keep up the extention during the day. I know I have good water flow and lighting. Is it a lack of food, all parameters are good. The digi that I bought from the LFS and other coral had good extention when purchased but it hasn't kept the same appearance in my tank. 80 gal with fug, Euro reef RS-135 skimmer. 2-250MH with 2-95 PC actinics. Turnover is around 60. Calcium reactor, kalk reactor, water changes. Any ideas, or am I being too picky? Zero phosphate and amonia.
