    Haven't changed anything aside from removing my internal skimmer and added a surface skimmer. Alk's been testing (redsea pro kit) at 8.4 for quit some time, dosing 15ml nightly of ESV 2 part. Ca's been steady at 425 dosing same amount daily. 12hrs apart.

    Yesterday I did a wc with an sg of 1.027 testing today. A little higher then usual, Oops me! Tested my alk today and it's reading 10.1 and ca still the same at 425

    Any ideas on why the rise? I'm not worried, just curious
