I have 1 20 watt 10K bulb and 1 20 watt actinic. Horrible lighting, but that's what I have to work with right now!
I purchased this tank from my LFS. It was a complete setup they had leased to a business. The business decided after 4 years to not renew the lease. I got a great deal on it. When the LFS moved the tank, everything got unsettled and the water parameters cratered. I have gotten it back to a good point now. I lost 8 snails and I starfish during that time, but no fish! I am going to let the tank settle for another month or so then add some fire shrimp and another green brain.
As far as filtration, I have what it came with....a trickle filter in the sump and a protein skimmer. Both are homemade by an acrylic guy the LFS used to have do a lot of their work. I am not sure what kind of sand it is. There is about 2 inches of it, by my Clarkii clown digs in it so much that he makes craters all the way down to the tank floor - this creates the 4 inch high mounds you see near the front! I think he wants an anemone! I have pretty well given up on smoothing out the hills in the sand. It only takes him about an hour to screw it up again!
