Scoutmaster I could be very wrong here but I think your furnace analogy is more like a CO2 sensor (not pH probe) just after the regulator. Thinking of a central heating bioler is just as good. The thermocouple (pH probe) is in the hot water (CO2 reactor) not in the flame (CO2 line).

Just my analogy about the furnace thing......To me it seems like you are putting the thermostat in the same room as the heater vent in a house with many rooms to heat

Hmm, lets see post a topic on a CO2 reactor, get close to 300 views, and the majority of comments deal with home heating. WTF....DC

Devildog,

I'm in the process of building one like yours... I like the concept and have been looking for an external reactor for some time...

Thanks! It looks great and keep us posted on how you like it and how it works...

Do you ever have to burp the air out of it? If so how do you do it with it hard mounted like that/

Have had no problems....DC

Ok thanks. I have an internal now. It works good but, I want to get it outta my tank. I like you design. I may give it a try.

could you put a petcock valve on the very top? If gas builds up on the top of the reactor you could open the valve and bleed it off, at least in theory. I'll probably build one of these and was thinking of installing one, may not need it, but it would beat shaking the reactor around. just a thought

TexasRock

Just so I am understanding this right... the water comes from the tank, through your fluval and then out to the reactor and then to the tank?

diablocanine

Yup, I have a new design now, check my "drilling my 55" post....DC
