Looking at T5 lighting and am wondering in you would use a clear cover under the lights. Have a 55 gallon long so it's 48"L x 12D x 20H. The dual strip I'm looking at is 6" deep and of course it would be above the water anyway. Would I need to get a glass top for the entire aquarium, a piece cut just for the area left open at the front of the tank? My brain is exhausted from trying to wade through the lighting info
Thanks for any input.
