Debating on a nano setup (~20 gal) and I have been researching all the options out there. PC lighting scares me a bit because it has not worked for me in the past. T5's look more promising, but I have only found one complete system that offers T5's (CAD). For the nano folks out there, have you been buying the tank separate from the lighting component and piece-mealing things together or have you been buying "full" systems? This will ultimately turn into my main Z&P tank, while also having an anemone perhaps (think of a crappy version of Marvin's tank). Thoughts on this would be appreciated.
