hygger CO2 Regulator with Motor Valve

Brand: hygger

Instead of a classic solenoid, this hygger unit uses a motorised valve with a built in timer, so CO2 can follow a daily schedule without an external plug timer. The body is dual stage with adjustable output pressure, and the manifold is expandable: two bubble counters ship as standard and further outlets can be added, which lets one cylinder feed two aquariums at different flow rates. Listed price on the maker's own store sits near 140 dollars.

Makes sense for aquarists running a pair of planted tanks side by side, or anyone tired of hunting for a spare outlet timer. The trade off is complexity: a motor valve and timer add electronics that a plain solenoid does not have, and extra bubble counters for further outlets cost more. Cylinder and tubing are separate purchases.
