I'm looking at options to light my 48" long tank.
My hood has fitments for a single tube about 38" long and I'm concerned that a tube of this length would be too bright for my fish, especially as the tank will be only 15" deep at the most. They are already scared of the 5W bulbs I have in my current tank!
I've been looking at some tubes made by Interpet which have built in reflectors, i.e. one side of the tube is painted silver. Would it be ok to just mount this upside down in the hood such that there is no direct light into the tank?
It's a fish only tank so only need enough light to see the fish by!
