quarentine coral and fish

hey everyone. I am about to start up again after tearing down my hundred ten gallon display tank. This time I want to preset up a quarantine for fish and corals. I'm going to use 20 gallon long tanks and I know they have to be on different systems but I have a question regarding the coral tank. I would like to use this as a quarantine / frag tank. What type of filtration and lighting should I set up for this tank.also any input on how to make these setups any better would be much appreciated thank you.

 

What type of corals? If your going to be attempting to keep the more expensive and sensitive sps than you'll probably want a decent fixture. A 2-4 bulb T5 fixture should be fine.There are many LED options for you as well. Depends on how much you want to spend.
Filtration, you just need a skimmer, and some mechanical filtration (sponge, floss or sock). Again depends on how complicated and expensive you want to make it for the corals types you want to keep.
