Added these corals from a previously established tank to my tank end of February. Going on 4 weeks later they've colored up but randomly have lost polyp extension in the past 1 week. First pic a strawberry shortcake and 2nd pic a blue polyp birdsnest.
Reduced my 2 part doser volumes to reduce my numbers. Currently parameters are:
Sg 1.025 to 1.026
Ca 475 (dropping about 2.5 per day, goal 440 or 450)
Alk 11.3 (dropping about 0.1 per day goal 9 to 10)
Nitrates and Phos unknown.
Will the high alk do this?
Last pic was the shortcake end of feburary. Brown but good PE.
