Well, I wish I could say it was deliberate, but it just sort of evolved that way. The tank is 16 months old. All the macro and turf algae appeared on it's own. I suppose you could call it a combined display/refugium. Anyway, here's what I've done with it.
June 06 set the tank up with dry dead sand and 18lbs of live rock. I'll update the web site with a photo of how it started soon. It's got a Whisper 30 HOB filter for circulation and to run carbon or phosphate sponge. And I originally had a Prizm protine skimmer, but later removed it and added a penquine 550 powerhead.
The tank ran with just the live rock till October 06, when I started added the corals and fish. Fish were only 1 red antenna goby and the Rainford's goby until I added the baby false perc clown recently. I've always had a very small clean-up crew, just 3 small hermits and 2 to 3 snails. I went through a lot of different algae on the way to where it's at now. Including hair.
So I guess the trick is to just be patient and don't add many critters that would eat the macros or turf algae.
