The ISTA CO2 Regulator with Single Pressure Meter

This compact regulator is a straightforward, reliable way to get pressurised CO2 into a planted tank, with a single gauge that shows cylinder pressure at a glance. We recommend it for hobbyists building their first proper CO2 setup or running a nano to mid-size planted tank, where a simple single-stage unit with clear readout covers the job without the cost of a fully featured dual-stage system.

The single pressure meter lets you see how much CO2 remains in the cylinder, so you can plan a refill before it runs dry mid-week. Its elegant, small footprint suits the tight spaces behind tanks in HDB and condo homes, tucking neatly beside a cabinet. As always, we suggest checking that the regulator matches your cylinder thread, and fitting a check valve downstream to guard against backflow during outages.

Add a solenoid and timer later to automate the day-night cycle. See the full CO2 systems range, and read our CO2 regulator guide, Singapore CO2 cylinder guide, and needle valve guide.
