Lighting

Reef aquarium lighting

Light is food for most corals. Our reef aquarium lighting includes LED fixtures, LED strips and mounting kits from trusted brands, including DII LED. There are lights for freshwater tanks too.

Choosing a reef light

Start with the corals you want to keep. Soft corals and mushrooms do well under moderate light. LPS corals like moderate to strong light. SPS corals need strong light. Then match the coverage to your tank's size, since one light rarely covers a long tank evenly.

Many LED lights let you set a schedule and a color mix. Most reefers use a blue-heavy spectrum, because it makes corals glow.

Common questions

How long should my reef lights be on?

Eight to ten hours of main light is a common schedule, with a slow ramp up and down.

Can new lights harm corals?

They can if they are too strong at first. So start at a lower intensity and raise it over a few weeks.
