Things You'll Need
- Fluorescent tube

Instructions
Unplug the aquarium hood and remove it from the aquarium. This is a safety precaution since you will be touching an electrical component that lies right above water. Cutting off electricity is essential to prevent electric shock.
Slide out the old fluorescent tube. These types of bulbs have two prongs on both ends and fit into narrow slots in the hood. The track that hold the prongs usually bends in one direction, requiring you to slightly twist the bulb as you remove it. This bend in the track helps hold the fluorescent tube in place.
Wrap the old bulb in newspapers. Throw it away in an outside trash bin or find out about recycling in your area. Placing the fluorescent bulb in your kitchen trash may cause it to shatter and puncture the trash bag. Some states may not allow you to dispose of the old bulb in the trash. Check with your refuse service to see if your state has a recycling program. The retailer where you purchased the bulb may allow you to bring in the old bulb, so it can dispose of it properly.
Set the prongs of the new fluorescent tube at the base of the tracks in the hood. Make sure the prongs line up on both ends. Slip the new bulb into the tracks. Carefully rotate the bulb, following the tracks, until it locks in place. It should fit snugly, but you should not have to force it in.
Place the hood back on top of aquarium. Plug in the hood and turn on the light switch. Your new fluorescent bulb should light up right away. If it doesn't work, unplug the hood and make sure the bulb is properly in place.
