Shedding Some Light on Planted Aquarium Lighting

No matter what type of aquarium you have—whether it's a planted tank, fish-only setup, or even a saltwater reef—every aquarist will eventually need a lighting fixture to illuminate the aquarium. In planted tanks, lighting plays a dual role: Aquascapers need it to monitor health and enjoy the view while aquarium plants require it to grow through photosynthesis.

All aquatic plants require light to grow. The duration and intensity of that light will vary depending on each individual species’ needs. In planted aquariums, “easy” plants are typically categorized this way because of their low lighting demands. Aquarium plants considered “high light” are often associated with more advanced setups, as stronger lighting is usually paired with higher nutrient levels and specific water parameters.

However, there’s plenty to consider! Aquatic plants like Anubias, Java Fern, Bucephalandra, Echinodorus, Cryptocoryne, Vallisneria, and various aquarium mosses can grow in low light conditions, but they can also thrive under high light. On the other hand, popular aquatic stem plants like Rotala, Ludwigia, and Alternanthera have higher lighting requirements and typically won’t grow well in low light environments.

Aquarium LED Lighting Overview

All aquatic plants require light to grow. The duration and intensity of that light will vary depending on each individual species’ needs. In planted aquariums, “easy” plants are typically categorized this way because of their low lighting demands. Aquarium plants considered “high light” are often associated with more advanced setups, as stronger lighting is usually paired with higher nutrient levels and specific water parameters.

Lighting	Nutrients	CO2
LOW	LOW Provided solely by nutrient-rich aquasoil or root tabs	Not required Plants may rely on natural CO2 produced by livestock or via a simple CO2 kit
MODERATE	MODERATE Use about half of the recommended liquid fertilizer dose. Aquarium plant soil is highly recommended.	Recommended CO2 should be used, but can be introduced slowly and adjusted based on plant growth. Use a drop checker to monitor levels.
HIGH	HIGH Full liquid plant fertilizer dosage is needed. Aquarium plant soil is required.	Required Providing it from the start and dialing in proper levels will help prevent algae from appearing.

Aquarium lighting that is too intense or kept running for too long can result in algae problems! The light fixture you choose has to match the plants you’re growing. Here’s an easy guide to help shed some light on lighting in a planted aquarium:

Aquascaper’s Tip: Almost all Glass Aqua planted tanks are high light demanding setups. However, we start off with moderate levels and slowly build the intensity as the plants grow week to week.

So many lights, so many model numbers—how do I even choose?

We were super confused when we first started the hobby too. BUT! It’s actually really simple: think of it as a numbers-matching game. Brands like Chihiros and Twinstar use model numbers like Twinstar 600E or Chihiros WRGB II PRO 60. All you need to do is match that number with your rimless aquarium’s model—or one that’s close to it. (Most lights come with adjustable legs now, so there’s some flexibility!) For example, both of the lights above pair perfectly with the Ultum Nature Systems 60U, a standard 60CM rimless tank. The same logic applies to larger tanks. A UNS 120U, which is double the width, would need two Twinstar 600E’s or two WRGB II PRO 60s.

The "60" in the light model refers to the aquarium’s width in centimeters—and 60cm is roughly 24”. So, a 60U would also be compatible with a 24” ONF Flat One LED light. Using that same logic, a 120U rimless aquarium (120cm wide) would need two 24” ONF Flat One lights. (120cm ≈ 48 inches!) Some brands also offer dedicated 120 light models—so in that case, you'd only need one fixture. But we thought this example would make it easier to understand. Easy numbers, easy math, easy lighting choices now, right?

Depending on the brand, this will vary. Twinstar primarily uses letter-based model names (A, B, C, E, EA, S). In general, the earlier the letter is in the alphabet, the lower intensity max brightness of the light will be. For example, the Twinstar A series is recommended for low light plants while the S series is designed for maximum brightness output.

Chihiros utilizes a similar lettering system - with the exception of the RGB Vivid or WRGB lines. RGB Vivid lights offer max lighting for planted aquariums and is their flagship model, whereas WRGB models are less intense but with the same premium build quality.

Some lights such as the Ultum Nature Systems Titan 1 are pendant style which means the light will require some form of suspension via an aquarium light hanging kit. We love hanging kits as they lift the light up and out of the way for a better viewing and maintenance experience.

Now that you have lighting down, be sure to check out the nano aquarium light options as well because these brands also produce cuter and smaller versions of their main lights to suit desktop and nano aquariums too!

Burning hot when it’s on

"I don’t know how fairly review this because what I didn’t like was how burning hot the lamp was once turned on. And it gave unnatural hues, too green."

— Anna T. (3/5)

Good light.

"So far is a good light. Enjoy the app to control timer and intensity. The light looks good on my uns 3n but the one on my 45u looks a little small for the tank. Good budge build light. Can’t talk about growth because both my lights are on new tanks."

— Mark G. (5/5)
