My tank PH ranges from 7.9 just before the light turns on to 8.2 when the lights are turned off. The tank consumes about 1dkh per day. At the moment I mostly dose during the day but I am thinking whether I should dose mostly at night to keep the ph up. I know people do this with Kalkwasser to keep the ph up at night. I have no idea when corals consume two parts to build skeletons. Does this mostly happen during the day or night or at the same rate all day? I heard kids grow taller when sleeping LOL.
