Probably a lot of different experiences and opinions on this one but I'll give mine and take it with a grain of salt (no pun intended) AB+ is fairly concentrated so dosing multiple times per day the dosage would be quite small unless you are running a large and well stocked system. AB+ as you may already know can stay out of the fridge for about a week as far as I am aware so there is more maintenance involved in the use of an auto doser for this particular supplement. I also use AB+ and dose every other day at night in one shot by hand at around 8 mil per 40 gal. You might look into an amino acid supplement that you can dose that doesn't require refrigeration if you are new to dosing and want to avoid cleaning tubes and refilling an AB+ reservoir every week... (this might be another topic) For me, I auto dose KZ LPS and KZ XTRA daily just for extra credit and it seems to help my corals get a little boost during the daylight hours. Those supplements are also concentrated so I dose each one at different times throughout the day. Long answer short, I personally don't think its necessary to spread out coral feeding throughout the day and just feed when the lights go down especially if you are running a system under 100 gallons.
