Compatibility

A flat ceramic diffuser designed to sit on the tank bottom, where the longest possible water column gives the CO₂ the most contact time. The CO₂ inlet points vertically, so the tubing runs straight down without a kink.

It suits any pressurised CO₂ system on standard tubing. A check valve upstream is required.
