You should dose multiple times per day to limit alk swings. Especially as your dose increases you'll want to add even more intervals to ensure good mixing and alk stability. I dose 4 times per day/night evenly spaced currently. I would like to add even more but it's kind of a pain to update dosing levels across a bunch of intervals. Especially with a new tank where alk demands are constantly changing and you need to alter the dosing levels quite frequently.
With a new tank with a low element uptake once a day is sufficient, since the daily swing ( especially kH) is low. As the tank matures and the corals grow you will need to dose more frequently to prevent intra day swings.
I have a 350 liter tank running Triton. Currently I dose 18ml of each the 4 elements a day spaced over 12 doses. My kH swing is around 0.1 a day and intra day is even less.
