Mel- great tank! any chance I can get you to to post tank-check/stats for us? real curious on some of your equip (especially wtf kind of lights you're running in 1st pic!)
re aquascaping, please consider custom-cast rockscaping! I'll try to find some pics and data, but i did this for a moray tank of mine and it was soooo cool! (took almost 1.5mo, iirc, for the custom rocks to finally become proper ph and get in that tank, but worthwhile! This was same approach used by aquariums to make their huge rock walls)
(oh and GORGEOUS eel! Chainlink moray was the first salt specimen i ever got, just wasn't ready at that point sadly (nor are most salt enthusiasts upon start..)
