Co2 Regulator And Cylinder

A pressurised CO2 system starts with a reliable regulator and cylinder, and we stock the full setup for Singapore planted tanks — ANS, ISTA and UP Aqua CO2 regulators (single and dual-stage, with and without solenoid), alloy and aluminium cylinders from 2L up, and complete plug-and-play kits. A solenoid lets you put CO2 on a timer so it runs only with your lights. Sizing tips for local tanks: a 2L cylinder suits nano and small planted setups, while 3–5L cylinders mean far fewer refill trips — handy since CO2 refills aren't on every corner here. Dual-stage regulators give steadier output as the cylinder empties, avoiding the end-of-tank dump that can gas fish. Always pair CO2 with good surface agitation overnight.
