I'm planning on purchasing this http://www.fishneedit.com/t5ho-4ft--2lamp-aquarium-light.html light once I figure out which bulbs to use. It will be going on my 90 gal eartheater community. There will be no plants. I know nothing about lighting at all and was thinking 2 whites at 10k? Or 1 white / 1 blue ? Not sure which route I should go Thanks
