Ya for people with low nutrient tanks, broadcast feeding is where it's at. However, people that don't run gfo, have big enough skimmers, and/or don't run bio pellets need to be careful, they can run into high nutrient problems if they are constantly broadcast feeding.
I'm running bio pellets with a big skimmer and I notice if I cut back on feeding for a few days, my zoos and chalices start looking pissed off. I do some broadcast feeding and up my fish feeding, and within a couple days everyone is back to being happy again.
Hot Dogs are GOOD!
