Lighting defines the success of every planted aquarium.
The Chihiros WRGB2 family is known for its accuracy, color brilliance, and smart control — trusted by aquascapers worldwide.
But which model fits your needs — WRGB2, WRGB2 Pro, or B Series?
Let’s break it down simply, so you can make the right choice for your aquascape.
Spectrum and Power Output
All Chihiros WRGB models offer a true WRGB spectrum (White, Red, Green, Blue) that reveals natural colors and enhances plant pigments.
| Model | PAR Output | Recommended Use | Notes |
|---|---|---|---|
| WRGB2 | High | Medium–high-tech tanks | Perfect color balance |
| WRGB2 Pro | Very High | Advanced aquascapes | Strongest PAR, ideal for red plants |
| B Series | Moderate | Nano/low-tech setups | Compact, elegant design |
📱 Smart Control and Design
Each light connects to the Chihiros App, where you can fine-tune brightness, color temperature, and timing.
This allows a natural sunrise/sunset effect that reduces stress for fish and promotes steady plant growth.
When paired with balanced fertilization from 2HR Aquarist, it creates the perfect light-nutrient synergy.
🌿 Light + Nutrition: The Perfect Combo
Even the best lighting can’t do its job without the right nutrients.
That’s where 2HR Aquarist APT fertilizers come in — designed to match the light intensity and CO₂ levels in your setup:
-
APT 1 – for low-tech tanks under B Series lights
-
