ummm, maybe I should wait til I acually know what I'm doing when it comes to aquariums.....
None of us know exactly what we're doing. There will always be debate on many, many topics. The different opinions you're hearing on lighting and lighting schedules are that, opinion.
I think the only 100% truth is that your fish should have at least a full days worth of light. Psychologicaly, even people get stressed if they aren't exposed to a normal day and night cycle, the same should hold true for fish.
You are doing exactly what you should be. Asking questions to gather information, both factual and subjective so that you can make an informed decision to suit your specific needs and the opinion you form on your own.
Take a breath, shake your head out, read through it all again, and ask any new questions that come up or ones that don't seem to have been answered.
