Welcome to the darkside
I have a similar background, kept saltwater for years and just got a nano started this July.
- ask lots of questions
- MAAST, Reef Central, and Nano-Reef are my fav places for info (although, personally, the nano-reef boards are way to harsh for my liking)
- 28 gallon JBJ HQI, with actinic upgrade

. It only took a couple months for me to come to the conclusion the biocube didn't have enough light for the corals and colors I wanted to see.

'tis expensive and addicting in saltwater land
