Planted vs Basic LED Aquarium Light: Which Do You Need?

Planted tank LED vs basic LED aquarium light compared: light intensity, spectrum, plant growth, algae risk, programmability and cost.

The short version

A basic LED lights the tank and grows low-light plants such as anubias and java fern perfectly well. A planted-specific LED delivers the intensity and spectrum demanding plants need, and adds programmable ramping that helps control algae. Buy the basic light for fish-focused tanks and easy plants; buy the planted light for carpeting plants, stems and anything CO2 injected.

Choose the Fluval Plant 3.0 LED if…

You want a carpet, red stem plants, or you are running CO2. Those plants fail under insufficient light no matter what else you do, and programmable ramping lets you dial intensity back if algae appears rather than reaching for a shorter photoperiod.

Choose the NICREW ClassicLED Plus if…

Your tank is about the fish, with anubias, java fern, cryptocoryne or moss. Those plants thrive in modest light and actually do worse under an intense fixture, which mostly grows algae if the rest of the balance is not there.

Frequently Asked Questions

How long should I run the lights?

Six to eight hours is a sensible starting point. Longer photoperiods are the most common cause of algae in new tanks, and plants do not benefit from light beyond what their nutrient and carbon supply can support.

More light means more growth, surely?

Only if carbon and nutrients keep up. Light drives demand; if CO2 and fertiliser cannot meet that demand, the surplus feeds algae instead of plants. Balance matters more than raw intensity.

Will a planted light hurt my fish?

No, but a sudden bright light in a dark room startles them. That is exactly what ramping solves, and it is why sunrise and sunset simulation is more than a gimmick.
