ANS Brass CO2 T Splitter for Planted SG Aquariums

This simple solid brass T-piece divides a single CO2 feed into two lines, ideal when you want to inject two planted tanks, or a tank plus an inline diffuser, from one regulator. It is the neat, low-fuss way to expand a CO2 setup without committing to a full multi-way manifold. The compact brass body sits unobtrusively on the airline run and stands up to the persistent humidity of a Singapore home far better than plastic alternatives.

Splitting CO2 does mean balancing pressure between the two outlets, so pair the splitter with needle valves if your tanks need different bubble rates, since a bare T will favour the path of least resistance. Because CO2 shifts pH in our soft local water, raise injection gradually on each tank and verify with a drop checker, keeping fish and shrimp comfortable rather than gassed, especially through the lights-off hours.

Fit check valves downstream to keep water from creeping back toward the regulator. See our cleaning and maintenance range, and our CO2 setup guide and CO2 diffuser guide cover pairing splitters with diffusers.
