The Power Center is an easy-to-use 24 hour timer and 8 outlet indoor power strip in one convenient unit. This has 4 constant-power outlets and 4 timer-controlled outlets (2 daytime/2 nighttime) to make your day and night cycle application easier to manage. When the 2 daytime timer-controlled outlets are on, the 2 nighttime timer controlled outlets are off. This feature allows you to control aquarium and terrarium environments with daylight, nightlight, heat source, moonlight, and wave-maker applications. The Power Center can control two sets of water pumps (total of 4 outlets) at alternating intervals of 15 minutes (minimum) or more to create a wave-maker application. The two sets of outlets will interchange between each other based on timer setting. This wave-maker application creates a natural rhythm in your aquarium that replicates ocean tidal movements.
