Frequently Asked Questions (FAQs)

1. How bright should aquarium lights be?

Most freshwater aquarium lights are rated between 5,500 and 8,000 Kelvin. Intensity and spectrum are less important in aquariums or with artificial plants, although some lights enhance natural colors better than others. A light that's too intense may promote algae, especially in non-planted tanks.

2. Can aquarium lights be too bright?

But in general, the lighting shouldn't be too bright for a regular tank since it could stress the fish. Too-bright lighting can also lead to algae growth.

3. Is 6500K good for aquarium plants?

Every website out there that claims 6500K is better for plants is purely a marketing gimmick. For aquarist purposes, K rating is useful when buying household lighting and re-purposing it for aquarium use.

4. What is considered high light for aquarium plants?

Roughly speaking, cool colours are rated over 5000k, and warmer colours are rating below. Daylight is 6500K, which is what many prefer for the planted aquarium. Plants are not overly fussed about the colour of your light in order to grow.
