5. Operating the PopBloom RL90
The PopBloom RL90 offers various operating modes and features through the Smart Life app to customize your aquarium lighting.
5.1 App Control Features
- DIY Mode: Customize a 24-hour lighting schedule. Set start and end times, and adjust the color and brightness for each of the four channels independently.
- Natural Simulation: Simulate natural phenomena such as sunrise, sunset, 24-hour auto cycle, 4 seasons, lunar cycle, and storm effects. This helps create a natural environment for your corals and marine life.
- Lunar Cycle: Activate a 29-day lunar cycle. The app will automatically update the light intensity to mimic the moon's phases.
- Lightning Mode: Stimulate vigorous coral growth with random lightning flashes. Run for a set duration.
- Slow Acclimation Mode: Gradually introduce new corals or acclimate your tank to the new light by slowly increasing intensity over a set period.
- Group Control: Manage multiple RL90 lights simultaneously from the app.

5.2 Spectrum and PAR Distribution
The RL90 features a full spectrum with 4 channels designed for optimal coral growth and coloration. The blue/UV spectrum promotes calcium absorption and Vitamin D3 synthesis in corals, enhancing their health and vibrant colors.
The light provides an ideal PAR distribution, ensuring even light penetration throughout your aquarium. Refer to the PAR distribution map for optimal light placement and intensity settings.
