interested in possibly building a refugium

[randoke]

and have questions after researching it on here.
1. I have a 125 gallon fish, live rock, and minimal corals. I currently have a sump underneath with a wet/dry with bioballs. My sump has a pump and a protein skimmer in it.
2. Can I turn this sump into a refugium and would I have to remove all the bioballs?
3. If so, I presume, I would add sand and LR to the sump bottom and have to add some sort of lighting, suggestions on light would be appreciated.
4. Alternatively, can you add a small aquarium to the side of my main one and run tubing and pumps to exchange water? I guess the benefit of this would be that I could have another tank in a way with rock and sand in it, maybe plants?
Any help would be greatly appreciated!!! :help:

it's not the most simple thing to set up. i'd recommend getting a good aquarist's book. they usually have a chapter on filtration and such and give good details on setting them up.
i'd help you but i've only read about fuges, not ever had experience with them.

Actually, refugiums are quite easy to install. If I was not getting ready to leave, I would break it down a bit. Number 4 is your best option though. Here, check this link out. I explained my fuge set-up here, and have detailed it with pics as well.
