First off, thanks for the comments and compliments..
I just got back online so I'll anwer a few questions.
The base is indeed a sink base cabinet. I bought two at Lowes as a matching set on either side of a fireplace. (I don't use the fireplace so heat from there is not an issue). For the tank, I built a free standing reinforced frame inside the sink base, so really the base is just for furniture quality 'show'.
Tank: 75 gallon tank (48" wide).
Filtration: Ecosystem refugium, model 3012
Pump capacity: 760 gph
Light : Custom Sealife PC's w/ moonlights. I have the three light sets (blue, daylight and moonlight) on timers to simulate the day.
Refugium is full of calupera, and the plant life in the front left of the tank is 'harvested' calupera I put in the tank for added plant life (filtration) and color. Plus after I cycled the tank I was a chicken regarding fish, so my LFS gave me some mollies she had acclimated to saltwater. "I" had babies, and now about 10 of them use the calupera to hide.
Regarding the firefish, my LFS said "one or more than two". They are out all the time. I had one that was a little shy at first, but not any more. They hover all day long and are awesome. But, the second 'dusk' turns to 'dark' they head for their hole in a piece of live rock.
I do have a 'reef' package doing their magic now, and all the 'stuff' going on in the tank is great. I was lucky to get hitch hikers including some featherdusters, bristleworms, spaghetti worms and I think mysid shrimp, and they are all doing super.
This set up is really straightforward, and with the liverock and refugium, I am trying to get a natural balance to minimize human intervention. My plan is to have a relatively low bioload in order to keep my natural filtration from getting overtaxed.
So far, so good. Any other questions, I'd be happy to respond.
