Getting sick of putting MA in

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.

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.

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.
