FAQ
Can this reactor be used in both saltwater and freshwater aquariums?
The TMC Reef Bio-Gro 2.0 M is designed for marine aquariums and is optimized for saltwater environments. It may not be suitable for freshwater setups.
How often should the algae be harvested?
Harvesting frequency depends on algae growth, but it is recommended to check every 1-2 weeks and remove excess algae as needed.
Is the lighting board adjustable?
Please contact customer service for details on lighting adjustment options.

The reactor works well in my 120-gallon reef tank. Algae growth is steady and nitrate levels have dropped noticeably over the past month. The lighting is effective and the design is easy to maintain. I appreciate the simple harvesting process.

Installed it externally and it fits perfectly in the corner of my sump. The algae production is consistent and helps keep nitrates in check. The only minor issue is that the lid takes a bit of effort to open, but it’s manageable.

Great product for reducing phosphates. The custom light spectrum really supports macro-algae growth. I’ve seen a clear improvement in water clarity after a few weeks of use.

Works as expected in a saltwater reef tank. The compact size makes it easy to install without taking up much space. I like that it can be used either internally or externally.
