hm hadnt given much thought to backgrounds, but im sure i can find something. I used carib sea arag alive bahama oolite. I was looking at ato units, it certainly would make life easier....
Great start! Don't forget to add an ATO to that thing ASAP. It just makes life so much easier.
That's a nice sized nano tank. Will you be putting a background on it to hide the gear?
Looks great, love the rockwork. What kind of sand did you use?
