A few years back I went from target feeding, to broadcast feedings heavily twice a day. I use my own mix of frozen, and 60ml of live phyto to an 80G display daily.
My nutrients leveled off, instead of spiking, then falling, then spiking again when I target fed.
My fish are happier, and my corals are fat, fluffy, colorful, and growing quite well. I have read many times over corals prefer ammonia to nitrates. More fish food, fatter fish that poop more often creating more ammonia. I have certainly seen a huge difference when I'm at a low bioload(fish wise), to a totally different tank when in that sweet spot of bioload for my tank.
I personally have noticed a big difference between feeding the tank, and target feeding coral.
Very firm believer in heavy in, heavy out.
