PRO-SE Series - New generation of our most popular Aquarium Dual Stage CO2 Regulator.

Completely redesigned with new pressure stabilization construction. Much larger internal springs provide safety and precision at the highest level.

Dual stage design minimizes the increase in output pressure as pressure drop in the gas bottle and will prevent end-tank-dump keeping the aquarium livestock safe and CO2 levels constant.
