Finnex Planted+ vs. Stock T8 Lighting

Starting with a 55-gallon planted tank, I initially used the standard T8 fluorescent light that came with the tank. While adequate for a year, it eventually needed replacement. The Finnex Planted+ was significantly brighter and offered a more vibrant light spectrum, enhancing the overall look of the tank.

The Planted+ also features a cool blue moonlight mode, activated separately. This provides a subtle glow even when the main lights are off, allowing for nighttime fish viewing. It's a nice feature, though preference will vary.

Finnex MonsterRay: Color Enhancement and Reddish Hue

The Finnex MonsterRay light is designed to boost the colors of fish and plants. While it definitely enhances the reds, oranges, and blues, it also casts a noticeable reddish tint on everything. This can make greens appear slightly washed-out or darker.

Despite this, the overall impact on fish coloration is positive, making them appear more vibrant and striking. The effect is especially noticeable on fish with multiple colors, like neon tetras.

Combining Finnex Planted+ and MonsterRay for Optimal Results

Using both the Planted+ and the MonsterRay allows for the best of both worlds—vibrant colors from the MonsterRay combined with the brighter, fuller spectrum of the Planted+. This setup is particularly effective in highlighting the various colors and shades within the tank environment.

Finnex Ray2: High-Light Intensity for Deeper Tanks

The Finnex Ray2 is designed for deeper tanks (taller than 18 inches) and delivers significantly higher light intensity than the Planted+. This makes it ideal for planted tanks that require stronger illumination to promote healthy plant growth.

It lacks the moonlight feature of the Planted+, but its superior brightness compensates for this. Using a Ray2 in a shallower tank might lead to algae problems due to excessive light intensity.

The MonsterRay excels at enhancing colors, though its reddish hue might not suit all preferences. For deeper tanks needing high-intensity light, the Ray2 is the clear winner, despite lacking the moonlight mode. Combining lights is also an option to get the best of all worlds.
