Is it designed to avoid promoting algae growth?

Yes, the SR-657 aquarium light can be turned on/off at the time you set, and the 20 levels of brightness can be adjusted to effectively prevent algae growth.

Is the battery included? Do I have to use batteries? How long does the battery last?

Yes, CR1220 batteries are included. The battery is only for memory function, and the LED light and controller can work without the battery. The battery only consumes power when power supply is disconnected.

Can this light help plants grow?

Of course! The spectrum of this aquarium light increases the intensity of red and blue light, which is more conducive to the growth of rhizomes and leaves of plants, and promotes the natural circulation of the water tank.

I'm having trouble programming, what should I do?

Tell us the lighting schedule you need (start time, end time, light color, brightness), and we will assist you in setting it up step by step. We usually reply in 12 hours.

I need to have the night mode start at 6pm but the number is skipping?

The night mode can't overlap with day mode. The night timer will auto skip the hours that is taken by day mode. Please edit day mode timer first.
