Just curious as to why some of you choose to have no background on your tanks. Thanks for your replies!
I have my tank on the kitchen counter which divides the kitchen and dining room. I like to be able to look in three sides of my tank. The HOB filter is at one side, the heater is at the other corner, and all the cords are unobtrusively run down the outside corners and along the base to get to the power strip.
I like it. It works for me.
