Getting sick of putting MA in

[Rodex]

So on both topics, once I got my TA down below 80 my pH now stays at about 7.8. I would prefer to have it around 60 or 70 but it seems like my pool likes a TA of 80. My fill water is 120, but we are the time of year where the rain will keep my pool more than full so going to give lowering the TA a try.

I too have an Atlas Scientific industrial pH probe, and I love it. The continuous monitoring really helped me get it all dialed in.

My automation is completely home grown (with the NjsPC) and it does everything I need. However, I am being goaded into doing an upgrade soon. Then the next step is a FC monitor. They are getting to the price when they might just be practical. But that is going to require some plumbing work that I am not a huge fan of.

This one?

Continuous monitoring would be really nice.

Yes that one.

I actually bought this whole kit. You can go with an EZO controller that is cheaper, but I like being able to go to the control box and see the pH. I also like the calibration buttons. I also put mine together before @rstrouse added those features to the Nixie controller.

Did you install yours into a 3/4” tee like the inline diagram on the site shows? How often have you needed to recalibrate, and do you just remove it from the tee to calibrate?

 

[rstrouse]

Mine is installed like this. And I simply unscrew it to calibrate it. The calibration is all done within REM but that only works with the EZO circuit.

Where in your plumbing did you tap into for that?
So the probe interfaces to the EZO controller which then interfaces to the Raspberry Pi?

 

[Katodude]

I am much more basic. I just put a T into my main plumbing. @rstrouse is better and I will eventually go that route. But at this rate it might take years.

Oh yeah, and I just unscrew it from the T to calibrate it. Right now it has gone several months without a calibration which is pretty good.
