Plant tank to Reef conversion

[trilinearmipmap]

I have a 58 gallon (36" long) FW plant tank and I am thinking of converting it into a softie/mushroom sumpless reef with a few modifications.

Questions about the lighting and a skimmer.

I have 110 Watts of PC lighting plus a 30 watt NO flourescent grow-light.

Will this be adequate, for mushrooms and softies, if not I can fairly easily upgrade to 2 x 96 Watt pc lighting.

Also I was considering a hang-on Remora or Remora Pro skimmer. I need it to be absolutely silent though as this is a waiting room in my office and I can not stand noise. Who has a Remora and what can you say about the noise these unit make?

Also can I keep a school of Naso tangs in this tank no just kidding.
