ITC ALR - Algae Light Reactors

ITC Algae Light Reactors – Efficient Nutrient Export with Plug-and-Play Performance

The ITC Algae Light Reactor (ALR) is a high-performance, award-winning solution for removing nitrate and phosphate from marine aquariums—designed with durability, efficiency, and ease-of-use in mind. Crafted from CNC-cut 10mm thick acrylic and powered by a precisely tuned full-spectrum LED light array, the ALR delivers exceptional macroalgae growth and nutrient export in a compact, contained system.

Key Features:

• Optimised for Macroalgae Growth
  Engineered to promote vigorous growth of Chaetomorpha (Chaeto) by illuminating algae from all sides, ensuring maximum light penetration and photosynthetic efficiency.
• Natural Nutrient Export
  Rapidly reduces nitrate and phosphate levels while increasing oxygen levels and ORP. The result: clearer water, healthier corals, and a more stable marine environment.
• Reverse Lighting for Enhanced Stability
  Designed to be run on a reverse light cycle (on when tank lights are off), the ALR helps stabilise pH, consume excess CO₂, and boost coral growth by balancing diurnal chemical swings in your system.
• Flexible Installation Options
  Can be installed in or out of a sump, run wet or dry, and integrated easily into most aquarium setups. Just plug in and grow.
• Easy Maintenance
  When full, simply harvest and discard excess macroalgae, along with the nutrients it absorbed. Leave a portion behind to regrow—no reset or downtime needed.
• Tried, Tested, Trusted
  Proven in homes and commercial systems for nearly a decade, with thousands of successful installations across the UK and beyond.

Three Sizes to Fit Any Aquarium:

• ALR1 – For tanks up to 500L / 130 US Gal
• ALR2 – For tanks up to 1000L / 210 US Gal
• ALR3 – For tanks up to 1500L / 400 US Gal

The ITC ALR is the most efficient use of algae filtration available today—delivering unmatched performance in nutrient export, stability, and long-term reliability. Whether you're running a nano reef or a commercial display, the ALR transforms nutrient control into a simple, effective, and low-maintenance process.
