I use a modified AC500 to grow chaeto as my HOB refugium. I keep Chemipure in the bottom & chaeto on top. It gets light from the MH system & works pretty well.
If you have a sump, you can always section off a part for a refugium to grow out some macro for nutrient export & to grow pods/live mysis.
The best, IMO, is an above tank refugium using a small tank set higher than the reef system with a small powerhead to send water up & an overflow to drain clean water & live pods down.
