Things You'll Need
- Measuring tape
- Aquarium hood
- Florescent bulbs
Instructions
Measure the length and width of your tank. You will need these measurements to determine what size aquarium hood you need. If you know the size of your tank and its specifications, i.e. 29 gallon long, 29 gallon high, that is a big help as well.
Purchase a full aquarium hood designed for the size tank you own. When you shop you should see both the dimensions and the tank size listed on each box. Choose the aquarium hood that matches the length and width as measured in Step 1.
Note the types of florescent bulbs included with the aquarium hood. The hood should come with bulbs already installed, but if not you will have to buy them separately. Even if the hood comes with bulbs, you should purchase one or two spares to have on hand. Look for bulbs that provide full spectrum lighting, especially if you plan to use live plants in your tank.
Turn the hood over so that the bottom is facing you. Insert the prongs from one end of the florescent bulb into the slots on the side of the hood and press them into place. Push the bulb into place and secure it at the other end.
Plug the aquarium hood into an electrical outlet and turn it on. Watch for the light bulb to come on. If the ends of the bulb appear dark or burned out, you should replace the bulb with a new one. Aquarium bulbs do not burn out all at once, but they do lose power over time. It can be difficult to notice a subtle change in lighting quality, but your fish and plants will definitely notice. Check your bulbs often and replace them when they begin to show signs of burning out.
