Ista Co2 Diffuser - 3 in 1 - Large

These are the most practical diffusers available. Into a single piece, you have a check valve, a bubble counter and the diffuser. Also very important is that the ceramic plate can be replaced.

Produces bubbles as small as a mist of CO2, generating maximum possible diffusion on CO2 in the aquarium. Undisputable quality and reliability. Compact size. Easy to install.
