Things You'll Need
- Floodlight
- Power cable
- Screw-in hook
- Chain
Instructions
Connect the wires of the floodlight to a three-pronged power cord. Match the colors of the wires, twist them together and thoroughly seal with electrical tape. It is best if the connection is outside of the sump area to prevent it from getting damp.
Hang the floodlight above the refugium with a small plastic chain. Screw a hook into the wood above the refugium and hang the chain from it. This will allow you to raise and lower the chain to adjust the light. Make sure there is adequate air flow around the light to prevent overheating. Consider adding a small fan inside the sump area to keep the light cool.
Plug the floodlight into a timer and plug the timer into a power outlet. Set the timer so that the refugium light comes on when the aquarium lights go out at night. This will help ensure there is plenty of oxygen in the aquarium at night and help maintain a balance of carbon dioxide.
