Sorry but I don't have a decent pic available...I could get one easy enough I suppose. The refugium is set up as follows...
There are 3 seperate containers...each is a rubbermaid 40 gal...water from my return out of the sump feeds the first stage where there is primarily macro algaes and a DSB with a pair of hang on filters(mechanical) for circulation. This first stage is heavily stocked with a large assortment of macros. Water exits via 2 overflows into the second stage that contains a DSB...about 30-40 lbs of LR and rubble...and primarily razor/feather/grape caulepras...the third stage is only a DSB and a few sponges for pods...very little algaes of any kind and what algaes are grown are remoed on a regular basis. The final stage returns via gravity thru the wall and back to the display.Very basic but sort of gettho set-up...I did find a pic from last September...not real good but it gives a little of a visual.
