Description
ITC Algae Light Reactor (ALR) – Advanced Nutrient Export for Marine Aquariums
The ITC Algae Light Reactor (ALR) is a high-efficiency solution for reducing nitrates and phosphates in marine aquariums. Constructed from robust 10mm CNC-cut acrylic and equipped with a full-spectrum LED light array, the ALR promotes rapid macroalgae growth, creating a compact and effective nutrient export system.
Key Benefits:
-
Optimised Macroalgae Growth: Designed to illuminate Chaetomorpha (Chaeto) from all sides, ensuring maximum photosynthesis and rapid biomass production.
-
Natural Nutrient Removal: Actively lowers nitrate and phosphate levels while boosting oxygen and ORP, resulting in clearer water and healthier corals.
-
Reverse Light Cycle: Operates when aquarium lights are off, helping stabilise pH, consume excess CO₂, and smooth diurnal chemical fluctuations for coral benefit.
-
Flexible Installation: Can be installed in or out of sumps, wet or dry, and integrates easily with most aquarium systems. Plug in and start growing.
-
Easy Maintenance: Harvest excess macroalgae when necessary; leave a portion to regrow without downtime.
-
Proven Reliability: Tested in thousands of home and commercial setups for nearly a decade.
Available Sizes:
-
ALR1: Tanks up to 500L / 130 US Gal
-
ALR2: Tanks up to 1000L / 210 US Gal
-
ALR3: Tanks up to 1500L / 400 US Gal
The ITC ALR provides a low-maintenance, high-performance approach to nutrient management, ideal for anything from nano reefs to large commercial displays. Achieve stable, healthy water conditions with minimal effort.
