What to Look For Before Buying

Choosing the right light is vital for marine life. You must match the spectrum to your coral needs. Consider the tank size to ensure proper coverage.

Check Spectrum and PAR

Corals require specific blue and UV wavelengths. Check the PAR values for your target corals. High PAR is needed for SPS corals. Low PAR works for soft corals. Ensure the spectrum supports photosynthesis.

Value Power and Coverage

Match the wattage to your tank volume. Larger tanks need more powerful lights. Ensure the light spans the entire length. Proper coverage prevents dark spots in the tank. This ensures even coral growth.

Rating Control Features

Look for programmable timers and dimmers. These features simulate natural day cycles. Sunrise and sunset modes reduce fish stress. Manual controls offer more customization. Check for easy-to-use interfaces.

Verify Build and Durability

Saltwater environments are highly corrosive. Choose lights with aluminum housings. Check the waterproof rating of the unit. Heat dissipation is critical for LED life. Look for efficient cooling systems.

Frequently Asked Questions

What spectrum do corals need?

Corals primarily need blue and actinic light. These wavelengths drive photosynthesis in zooxanthellae. Some corals also benefit from UV and violet light. A full spectrum helps with color pop.

How much light is enough?

Light needs depend on coral type. SPS corals require very high PAR levels. LPS and soft corals need moderate light. Always check your specific coral’s requirements.

Do I need a canopy?
