The ISTA I-533 CO2 Regulator System for Planted Tanks

This is a near-complete CO2 starter package, bundling the ISTA regulator with the accessories most planted-tank keepers otherwise buy piece by piece: a CO2 resistance tube, bubble counter, brass check valve, a nano diffuser and tube suckers. We like it for hobbyists setting up their first injected tank, since matched components take the guesswork out of fittings and reduce the chance of mismatched threads or leaks.

The included brass check valve is genuinely useful in Singapore, where monsoon-season power cuts can reverse pressure and pull tank water back up the line, and the bundled bubble counter lets you dial in your injection rate from day one. Note this regulator ships without a solenoid, so CO2 runs continuously unless you add one; many local keepers fit a solenoid and timer to switch it off overnight.

An upgraded diffuser option is also available if you want finer bubbles. See the full CO2 systems range, and read our beginner CO2 kit guide, solenoid regulator notes, and planted CO2 guide.
