One of the easiest ways to transform the appearance of your biOrb aquarium is by upgrading to an MCR lighting system. Whether you’re looking to enhance the colours of your fish, create a more striking display, or simply modernise an older setup, biOrb’s Multi-Colour Remote (MCR) lighting offers a simple yet effective upgrade.
With a choice of colours, adjustable brightness settings, and remote-control functionality, MCR lighting allows you to customise your aquarium’s appearance to suit your home, mood, or aquascape. For many biOrb owners, it’s one of the most popular and rewarding upgrades available.
In this guide, we’ll explain what MCR lighting is, the benefits it offers, how to determine compatibility with your aquarium, and how to install and get the most from your new lighting system.
What Is biOrb MCR Lighting?
MCR stands for Multi-Colour Remote.
Unlike standard white LED lighting, MCR systems allow you to control the colour and brightness of your aquarium lighting using a handheld remote control.
Depending on the model, MCR lighting typically offers:
- Multiple colour options
- Brightness adjustment
- Colour fade effects
- Colour-changing modes
- Remote operation
- Energy-efficient LED technology
The result is a highly customisable aquarium display that can look completely different at the touch of a button.
Why Upgrade to MCR Lighting?
Many biOrb aquariums come fitted with standard white LED lighting, which provides excellent visibility and low running costs. However, MCR lighting adds a whole new level of visual flexibility.
Enhanced Aquarium Appearance
Different colours can dramatically change the look of your aquarium.
For example:
- Blue lighting creates a marine-inspired appearance
- White lighting provides a natural daylight effect
- Purple and pink tones can highlight decorative elements
- Green lighting creates a striking contemporary look
Many owners enjoy changing colours depending on the time of day or room décor.

Does MCR Lighting Benefit Fish?
Fish generally care more about consistency than colour.
The primary benefits of MCR lighting are:
- Visual enhancement
- Aquarium aesthetics
- User enjoyment
However, maintaining a regular day-night schedule remains important for fish health.
Creating a Proper Lighting Schedule
Regardless of colour choice, aquarium lights should not remain on continuously.
A typical schedule is:
8–10 Hours Per Day
This helps:
- Maintain natural rhythms
- Reduce algae growth
- Improve fish wellbeing
Timers can be useful for maintaining consistency.
Common Installation Mistakes
Avoid these common errors:
Purchasing the Wrong Model
Always verify compatibility before ordering.
Overlooking Power Connections
Loose connectors can cause intermittent operation.
Leaving Lights On Too Long
Excessive photoperiods can encourage algae.
Ignoring Remote Batteries
Many initial setup issues are simply caused by flat batteries.
Maintaining Your MCR Lighting System
Fortunately, maintenance requirements are minimal.
Recommended tasks include:
Keep the Light Lens Clean
Wipe away dust and mineral deposits periodically.
Check Connections
Inspect cables during routine aquarium maintenance.
Replace Remote Batteries When Needed
Weak batteries can reduce operating range.
Avoid Water Exposure
Keep electrical components dry at all times.
