I was wondering if anyone had any suggestions in how to build a refugium for a 90 gallon tank. What do I need (lights, sand, tank, flow, etc). Thanks for the help :P

I like these two links for DIY sumps/refugiums.

Thanks for the links Sammy!

I have yet to actually buy anything extra for a refugium with the exception of lighting. Typically I use an extra deep sandbed and buy about 50 pounds of base rock (55 gal fuge for my 75 gal). I just plumb it inline with my sump. then add gracileria. I am using 2X40 Watt No lighting on 24X7. Xenia and colts and gracilera and calurapas have filled the rest of the tank.
