How do you change the lights on the bottom of the tank?
I noticed there's instructions on a coffee table aquarium. I'm interested in building one for my goldfish carp. When I saw the way it was done, I had a few questions to ask. Such as, how do you change the bulbs to the lights since they're on the bottom of the tank, zip tied to the shelf, and are facing away from you? How do you gravel vac the bottom when you need to do a water change?
