Calcium Reactor control by APEX?

[maidia]

Who run the Calcium Reactor and control by APEX? Can you share your program? Thanks

I just use the pH control wizard to control the co2 solenoid. Set it where you want the pH range inside your reactor.

I do Mai. Here is my programming.
Fallback OFF
If CalRx > 6.60 Then ON
If CalRx < 6.50 Then OFF
If Outlet Return = OFF Then OFF
If DT-pH2 < 7.85 Then OFF

Don, thanks..is the CalRX conected from the APEX module or conected to CO2 PH controler?

 

[Drdavis]

I should probably clarify a couple of things. There is a plug to the main calrx pump and that is just connected to a power strip. I have a needle valve that controls the effluent being dripped back into my pump. I have heard of some people who use a peristaltic pump to pedicels control the drip (not sure why anyone would do this when a needle valve does just fine).

Finally, yes Mai I have the co2 controller plugged in to the EB-8 outlet and that is where I took the programming from. You also need the PH probe for the calrx attached to your apex as well.

On the graphs on the left you will see a graph labeled CALRX my program is what creates the sawtooth. I also have slowed my bubble count so there is a nice sawtooth versus a fast reaction when the PH is too high.

Don,
I got 2 ph probes,1 plug into ph module of the apex and 1 into PH/ORP of the apex module. You think that ok or not?

 

[Drdavis]

Yes Mai that is exactly the way I have mine. I put one in the DT and the second in the top of the first calrx chamber.

Yes it is Don...I name PH1 and PH2..I need to wait for the PW10 pump on the way..so will ask more question later. Thanks

Don, how about the bubble counter? One bubble for 3 seconds?

 

[Drdavis]

That is a fine point to start. What the bubble count does in my mind is it controls how fast the CO2 will lower your PH back down toward 6.5. You do not want it to be so slow that it cant keep up but you also do not want it so fast that your PH will swing drastically.
