Another use for frequent dosing throughout the day in a reef tank is 2 part alkalinity/calcium. It works best if added at regular intervals through out the day. The more start times throughout the day the better for this application. I have been using the old controller with ac powered dosers. It only has 4 start times per day and it causes some wide swings in ph and alkalinity.
