found this today while surfing-posted it for bleached corals.i run my tanks on natural or live foods-very rarely using pellets and never ready made foods except for flakes in some tanks.in my frag tank i feed twice a day with rotifers and a bit of phyto to feed the rotifers.the rotifers eat the phyto which enriches them,and the coral can catch the rotifers in the water column
