Running CO2 to more than one tank from a single cylinder means splitting the line without losing control over how much gas goes where. The Dymax CO2 Three-Way Splitter divides a single CO2 source into three independently adjustable outputs.
Why a Splitter Beats Multiple Cylinders
Running a separate CO2 cylinder per tank adds cost, refill hassle, and clutter. A splitter lets one cylinder supply multiple planted tanks, with individual control over each line so tanks with different CO2 demand don't have to share a single fixed rate.
What the Splitter Offers
- Three independent outputs from a single CO2 source, each individually adjustable.
- Simplifies multi-tank fishrooms that would otherwise need separate cylinders and regulators per tank.
- Compact inline design that fits into an existing CO2 setup without major reconfiguration.
How to Use It
- Set each output individually to match each tank's specific CO2 demand rather than assuming an even split.
- Use a bubble counter on each line to monitor and fine-tune output per tank.
- Check for leaks at each connection point after installation, since more fittings means more potential leak points.
