Just changing the gain of the current sensor wouldn't do it.
It can't take not even 1psi.
Water pressure in the pipe is very minimal and that's why we use such small range sensor.
It requires a mod to use a sensor that can measure the range of the CO2 tank.

Sorry 850 to 900

Are you sure it is not 100?

Yes positive. Gauge is 0 - 2000 psi.

Look on link I posted to the exact regulator I am using. First gauge, pressure on tank, is 850-900 PSIG

What would be cool would be this, plus the ph expansion plus a co2 regulator and have an all in one carbon reactor kit. AlanM built a pwm solenoid I believe that could be used. Let me see if I could dig up the link.


I would buy this! This is a major failure point in my system that keeps me up at night. I lost my entire tank in an ALK spike, due to no CO2. Lost few $1000 in coral.

This is the regulator I am using:

Would it be possible to get a peristalic pump as well to feed the reactor? Would have to be continuous duty.


Why would you have an alk spike with no gas? Are you talking about a drop? If it's caught within a day or so, I don't think you'd have too much ill effect. Drops are MUCH less harmful than spikes ime.

I use the same carbondoser regulator and a masterflex peristaltic pump for my setup and it is fantastic. I would still love to see some more advanced integration with the RA as I believe all the elements are here both minds and hardware.

For that kind of pressure, the sensor can't be pcb mount like the one user on the water level expansion.
It would have to be connected with a lead and it cost quite a bit more. Rough estimate would be around $150

I am still in, my corals cost me way more!

If you have an integrated system pH, controlled output Solenoid, Pressure Sensor, continuous duty Peristaltic pump, etc I would buy. My basic CARx sytems is $1000+.

Imagine to be able to have full control of the CalRx. Especially if I can control output via a continuous duty peristaltic pump. This would be the ulitmate Calcium Reactor. If someone could just automate the Alk testing reefing would be much easier

I am a time limited Reefer. I could literally go a few days with no time to mess with the tank. If I could get a reminder my tank is near empty, I can time a trip to Air-Gas Fill plant or Homebrew Store to get a CO2 fill.

Not spike, but swings in my ALK have caused my tank to go haywire. Killed a tankful back when I first started the tank.

Wow I hadn't considered what Alan had said about using the ph to control the solenoid and then with the pressure guage monitoring the tank you'd maintain a pretty rock solid reactor setup...so we have 150 for the sensor, 110 for a ph expansion. Figure around 350 for a full solenoid/ph/digital gauge. We already have the functions pretty much to have a completely integrated calcium reactor setup.
