Aqua Medic CO2 Reactor 1000 Information

Product Manuals & Documentation

Closed external CO2 reactor for aquaria up to 500 gal

This is a hermetically sealed reactor for the introduction of CO2 into large live plant systems. This powerful unit is designed to efficiently dissolve rising CO2 bubbles in strong counter-current water flow. The robust mounting plate enables it to be easily mounted outside the aquarium or inside the cabinet. Able to provide rapid CO2 introduction for systems as large as 500 gallons, the Reactor 1000 has proven to be a capable favorite among keepers of sizeable live plant systems. This is supplied with a strong holder. Accepts 1/2" tubing. Total height: app. 15 in; diameter app. 3 in.

Comments: they restrict flow of water. It back pressurizes the entire system, might be ok for small setups but not good for ¾” or bigger plumbing/hoses. The nipples that attach to the unit are weak, and gave in to pressure from a 1200GHP pump after 2 mechanical filters and one bio. For $20 at ACE I made one it will never break or leak.

Comments: The Aqua Medic CO2 reactor is built extremely strong. I've had this on my systems now for over 4 years and I must say it works as it did day one. All the hardware is built to last and has. If anyone is looking for a great reactor for saltwater I must say this is it. Cost more but there's a reason for that - you will not be replacing it next year!
