My corals get phyto too and that's about all I feed them. Very occasionally I will spot feed my LPS
with meaty foods, but that's it. I'd feed about 2-3 times a week if you wish on feeding, but make sure to keep up on water changes either weekly or bi-weekly.
On a side note, is the orange carnation that you mention a Dendronepthya carnation coral? If is, they are very hard to keep alive, because they require a LOT of microfauna, and I would target feed that coral nightly, and with a good amount. They lack zooxanthellea, so they NEED good, nutritious food to survive.
