The Lighting Challenge: A Deep 110-Gallon Tank

I embarked on a quest to illuminate my substantial 110-gallon aquarium. The depth of the tank presented a significant hurdle, as my initial lighting setup, an Aquatic Life 10,000K reef light and a T8 6500K, proved insufficient for the plants I'd added. The light simply didn't penetrate the water column effectively, leaving the lower regions dimly lit.

This prompted a consultation with Cory from Aquarium Co-op, a well-respected source in the aquarium community. His recommendation? The Fluval 3.0 plant light. Intrigued, I decided to give it a try, hoping it would finally solve my lighting woes.

Fluval 3.0: Setup and First Impressions

Installation of the Fluval 3.0 48-inch LED bar light was straightforward. Initial observations were promising; the light appeared significantly brighter than its predecessors. Using the accompanying app, I explored various lighting modes: pink, blue, cool white, warm white, and pure white. The pure white setting delivered the most intense illumination, dramatically improving the overall brightness.

I’m currently cycling the tank, which includes a beta fish, some killifish and a Cory cat. Even with the tank's depth and size, the Fluval 3.0 provided much better light penetration than my previous attempts. Initial tests with easy plants are showing promising results.

While the red and blue settings didn't significantly enhance plant growth in my observations, the pure white and warm white settings proved highly effective. I found manual control to be the most useful for achieving optimal lighting conditions for the tank’s inhabitants.
