Has anyone used the Red Sea CO2 Reactor 500 w/Pump? Does it work with a diy co2 setup rather than just the pressurized?

How about the glass and ceramic diffusers? I was reading on some site and it made it sound like you had to replace one of these every so often. Is that true?

Any help would be great! Thanks!
 
Subscribing...

I just built my own reactor out of PVC pipe. It's a modified version of Rex Grigg's:

http://www.rexgrigg.com/diy-reactor.htm

The differences with mine are ball valves at every connection, it's roughly 10" longer, and rather than a cap at the bottom, I installed a reducer with a connection for draining the tank from my cannister filter outlet (which has a panty hose cover on it!). I set my outlet at mid tank...so I can do a 50% water change without even being around the tank lol. Once the suction breaks, I move the hose over to the kitchen sink, and away I go refilling. Only way to do 150gal water changes =/.

Anyhow though, the size thing is also why I went with a reactor rather than a diffuser. I really liked the tiny tiny bubbles, but it would take multiple diffusers to get the sort of surface area I need to Co2 inject 300gal.

Anyhow, hope the link helps, and I'll see about getting some pictures up of my reactor (it's built, but not installed yet!)

C.Anderson: it would be fun to see your reactor. Right now i am only planning on using CO2 in a 30, and a 20L (heavily planted.) So i dont have quite the same problem. I have a simple diy diffuser now in a 75gal, that does not seem to be effective at all. (I am planning to change this tank over to a cichlid tank with rocks, java fern and moss.)

Fordtrannyman: I have been leaning towards that one. Somehow the other seems too simple...
