Oxyprax needs next to no maintenance beyond a regular clean to keep it free of debris — see the How to Clean Oxyprax guide under Documents & Resources.

Bubbletech Oxyprax Tubing

Q: How much Oxyprax do I need?

Multiply 2 LPM per metre by your diffuser length, or divide your total required gas flow by 2 LPM per metre to get the length needed — keep each individual diffuser run to 200 cm or less.

Q: What bubble size does it produce?

Under 0.5 mm, from roughly 120,000 micro-perforations per metre.

Q: What pressure does it need?

1 bar working pressure at the diffuser, plus enough to overcome the water depth it is set at.

Q: Does it need weighting?

Yes — Oxyprax is not self-weighted and needs additional weight to hold it in position.

Q: Do I need to soak it before use?

Yes — soak every new diffuser in water for a few hours so the micro-bubbles form as intended.

Q: How does it differ from Airprax and the Colorite Aero-Tube range?

Oxyprax is built for pressurised gas such as oxygen, ozone or CO2 at 1 bar, Airprax is the air version at 0.35 bar, and Colorite Aero-Tube is a coarser leaky-hose product for blower air at 1 PSI.

Micro-bubble diffuser tubing for dissolving pressurised oxygen, ozone or CO2 into tanks, raceways and transport systems.
