I have a 29gal that I want to be low-tech mediumish light. Could you give me some ideas? I currently have one 17watt t8 over it which I'm sure is reaallly low light right? From what I see T5HO lights would be too much since I don't want to do CO2.. I was trying to look into T5NO lights but all I see on sites like Marineland and Foster and Smith are HOs, so what is an NO sold as? Anyways now that I've thoroughly confused myself can you folks just offer some ideas and tips for lighting this baby?
