Absolutely, just kicking around the thought looking to see whats new ..For any size tank, first figure out what you are going to keep in it. Also, with a nano, there are going to be limitations since a lot of expensive equipment isn't cost justified. Done properly, a nano can be a real gem.
Welcome back to RS, good to see you getting back in the game ! Be sure to start a new tank thread when you get going so we can follow along
What size nano tank were you considering? Love the RSM 34 gallon tanks...
If you prefer LED, you might want to look into some of the Reefbreeders fixtures as well.
