Description

The Me CO2 Extender Ultra is an expansion module for the Me CO2 Regulator Ultra that lets one CO2 bottle supply two diffusers at the same time.

A second bottle and regulator for a second tank doubles the cost and the space. The Extender Ultra splits the supply from one regulator instead, which also helps on long aquariums where a single diffuser can't spread CO2 evenly.
