Switching from saltwater

Ok so I have a 90g DSA reef ready that I'm going to be switching to fresh as salt is to much work and I'm gone for work to often to have the wife take care of it, it's been dry for a year now anyway, what do I need to do for filtration though? I have a protein skimmer is that to much or to little or does it even work in FW?
Also was planning on just using my Tek T5's for lighting still and probably either doing angels or cichlids I haven't decided on that part yet.

 

no,the skimmer won't work,the density of saltwater is heavier than fresh,but i ran one for a while on a freshtank just for oxygenation,and switch your light bulbs out with around 6700k and you could easily start a planted tank.

 

All you need for fresh is somewhere to put carbon, and a source of mild water movement.

I would go planted, so you don't need GFO or anything like that to keep algae from growing.

 

Get a canister filter that pushes 2 to 4 times the tank volume.
