Hey everyone,
I've been trying to research lighting as I know I need to upgrade my 4 bulb T5 lighting for my 55 gallon. I have seen on several site, people talk about 30, 60, 90 degreee lighting or optic. Can anyone easily explain this? Not sure what effect it has and which I need.
Thanks in advance.
