  • Minimizes the visibility of CO2 equipment in the aquarium
  • Ensures maximum dissolution of CO2 in aquarium water
  • Allows for more consistent dosing of CO2
  • Compatible with 16 mm ID/22 mm OD hoses

The 17 mm glass Inline Diffuser is a pollen style inline CO2 diffuser that is placed in the outflow line of the filter or aquarium pump to efficiently diffuse CO2 gas into the aquarium. This placement of the diffuser avoids the need for a diffuser in the aquarium and significantly reduces the visibility of the CO2 injection system in the aquascape. This also allows for more rapid diffusion of CO2 into the system and can allow for more consistent levels and reduce waste of CO2 or overdose of CO2

Compatible with 16 mm ID/22 mm OD hoses. Compatible with 4/6 mm (1/4") - Standard Airline Tubing. Suction cups included.

Matthew ★★★★★

The CO2 haze is finally gone—my tank looks crystal clear now, and the inline diffuser dissolves gas way more consistently than my old airstone setup. The 16mm/22mm hose compatibility was a perfect match for my canister filter lines.

George D. ★★★★★

The 17mm size fit my existing hoses perfectly, and I love how the bubble counter lets me see exactly what's going in. CO2 dissolves so much more efficiently now that my drop checker stays steady.

Daniel ★★★★★

I was tired of seeing the ugly reactor coil in my tank, and this 17mm glass piece fixed that completely. The way it dissolves CO2 into the water column is visibly more efficient, and it cleans up the whole setup.
