Reef tank without fish

[Dan1789]

I need a little advice. After losing all but 4 of my fish to ich, I have decided to go fallow for 12 weeks or so. I have my 4 fish in QT and my tank has just my corals. It's been about 3-4 weeks. My question is how should I go about providing nutrients for the corals and food for the CuC. I've been feeding reef chili every other night and broadcast feeding fish food (mix of rods, mysis and a frozen mix cube) every other day as well. Once a week I give the hermits and snails some nori on a rock. Any advice would be welcome. My tank is mostly LPS and softies with a few new sps frags.
