Nice tank. Tell us more about it. What filtration do you use and how many fishes. I'm interested to know because i'm currently setting up a Deep blue 60g cube as well.
Right now i have a 30g sump and a total of 100 lbs of live rock. I use filter socks which i switch out weekly. I am currently running chemipure elite but i also plan on adding a small skimmer, so far so good though.
My current stock list is 3 green chromis, 1 neon goby, 1 ocellaris clown, one fire fish, 2 cardinals, 2 sexy shrimp, 1 cleaner shrimp, 1 watchman goby and 1 pistol shrimp.
