Realize I haven't updated in a while - I have been checking in though and reading the threads. I've finally started making some progress on my brood stock set up here are some pics: I've set it up using 4 20g longs (top 2 divided in 3 sections each / lower 2 in 2 sections each) which will house 10 pairs. Each section has it's own overflow / return. The tanks are offset and will use one light for all of them. The sump is made up of a raised 20g high which will house just LR and will overflow into a 40 bdr which will house my euro reef 180 skimmer, a UV sterilizer and a fuge.
