Lighting does two jobs: it shows off your fish and, in a planted tank, it powers plant growth. The right unit depends on whether you keep plants, how deep the tank is, and whether you want simple illumination or programmable control.

Match the light to the tank. A fish-only tank needs enough light to view the fish; a planted tank needs the correct spectrum and intensity for the plants you're growing. Check each product for tank size, spectrum and mounting details before ordering.

Frequently asked questions

It depends on the plants. Low-light plants like anubias, java fern and cryptocorynes thrive under modest LED lighting, while carpeting and high-demand stem plants need stronger, correct-spectrum light (often with added CO2). Matching light intensity to your plant choice — rather than just buying the brightest unit — is the key to healthy growth without an algae problem.
