The Chihiros Doctor 5 is a compact, smart device that helps keep your aquarium healthy by combining algae control, temperature monitoring, and remote app control in one unit. Its built-in display lets you check readings at a glance, while a magnetic connector between the replacement cartridge and main unit makes maintenance quick, secure, and waterproof.

Using micro-electrolysis technology, the Doctor 5 generates powerful oxidizing agents that target harmful algae and bacteria, helping to improve water clarity and lower the risk of disease for your fish — all without harsh chemicals. With three operating modes (Plant, Fish, Shrimp) and easy Bluetooth connectivity via the MyChihiros app, this all-in-one tool supports the well-being of your aquarium and its inhabitants, making tank care simpler and more effective.
