I would thin 3 times a day for seaweed selects might be a bit much (and expensive to in the long run). What I like to do is put some Romaine (I hear the moans already but I am not a fan of seaweed selects) in a lettuce clip for a few hours and let the fish graze (you can do the same with your seaweed selects just roll it tight so it does not fall apart to fast). In my case my fish have always gone nuts for Romaine and when I tried seaweed selects they would not eat it not one fish would eat it strange huh. I give them some a couple 3 times a week and now in the summer I grow my own in my wife's garden and it is very soft and they eat every bit of it except the stem. In fact my Clown Trigger is the first to it in my big tank followed by the Blue Moon and Majestic Angels. In my 65 the Sailfin Tang and King Angel and even the Cleaner Wrasse are the first to it. Anyway if you have the time multiple feedings do no harm but time is not always kind to us for feeding our fish.
