Carbon dioxide regulator designed to improve CO2 delivery and support healthy plant growth in planted aquariums. Key benefits Efficient CO2 regulation: Designed to increase CO2 dissolution and improve diffusion efficiency so more carbon is available to plants where they need it. Supports photosynthesis: Promotes better photosynthesis by enabling higher local concentrations of dissolved carbon dioxide (and dissolved oxygen), helping live plants grow healthier. Spacesaving, compatible design: Compact and lightweight, with a curved glass connecting trachea that fits tanks up to 90 cm without taking up unnecessary space. Durable, clear construction: Made from quality crystal glass that resists acid and alkali, is of etching, and offers transparency for a clean, longlasting look in your aquarium. What this product does for you Delivers CO2 more effectively into the water column, improving the rate at which carbon dissolves and becomes available to plants. Reduces visual clutter and preserves aquascape aesthetics thanks to its clear glass construction and compact profile. Withstand typical aquarium conditions due to acid and alkaliresistant crystal glass. Features at a glance Function: CO2 regulation and improved dissolution/diffusion efficiency. Material: quality crystal glass — acid/alkali resistant, no etching, transparency. Size/compatibility: Compact fit for aquariums under 90 cm; lightweight and spacesaving. Design detail: Curved glass connecting trachea for easy placement and unobtrusive installation. Use scenarios Planted freshwater aquarium up to 90 cm where you need efficient CO2 diffusion without bulky equipment obscuring the view. Small aquascape or nano tank that requires precise CO2 delivery while maintaining a minimal, clean appearance. Shrimp or community tanks with live plants where stable photosynthesis support helps maintain plant health and water quality. Practical notes Place the Carbon dioxide regulator where the curved glass connecting trachea can run unobtrusively along the tank wall; the compact design minimizes interference with aquascaping. Regular visual inspection of glass components will help maintain transparency and longevity; the crystal glass construction resists common aquarium acids and alkalis. This Carbon dioxide regulator provides a compact, durable, and effective method to improve CO2 availability and support healthier plant growth in tanks up to 90 cm.
