Aquarium power centers and timers are essential for efficiently controlling tank lights, pumps, and other electrical devices in a saltwater aquarium. Not only do they regulate day and nighttime conditions for your fish, but also they can power your other devices to prevent them from using too much energy or tripping an outlet.

To help you find the best one for your needs, here are the best aquarium power timers and centers to add to your set-up.

What to Look for in Aquarium Power Timers and Centers


Given the extensive amount of equipment aquariums need, you likely have many different types of plugs. Take a moment to observe what types you have and find a power timer and center that will accommodate each and every one. Also, consider the capacity of your outlets. You don't want to buy a power timer or center that will cause them to trip.


Whether you spill water during maintenance or your tank leaks, accidents can happen. To help you prevent your power centers from getting wet, look for one that has a splash-resistant cover or can be mounted on the wall. Also, consider finding one with surge protection to keep your equipment safe from burning out.


Look for a power center that combines timed-outlets and constant-power outlets. This will help you maintain all your equipment in one spot, including the ones that need to be off during certain times of the day. Also, consider finding a power strip with separate power buttons for each plug. This can be especially helpful if you need to cut the power to one device without unplugging it, while the others stay running.
