@Ranjib
very interseting. thanks for sharing. I want to have this, if it helps all of us. I bet for calcium reactor usage as well as planted tanks this is fairly critical. I dont know to what precision though. But it does not matter really, at some point we'll shoot for a generic purpose titration system which will involve an accurate ph monitoring system, syringe pumps, and macros. So, we'll need a good ph measurement mechanism, one way or other.
Now that is a case for very high quality probes, pH buffered solutions, and calibrations. Like BT mentioned above, the line is broken at 7 pH, so the 4 to 7 pH slope is meaningless for a reef tank for example. But for an alkalinity titration or a freshwater planted tank, it would be absolutely crucial.
So Diamond1 will be the alkaline guinea pig, and ill be the acidic guinea pig!
I love that this project has freshwater aquaria interest and applications. It is fun to think about, and one day I would like to have a planted tank again.
A good planted tank can be fun to do. My current tank is soft water, acidic. My tank before I moved was hard water, 8.0 ph, livebearers and all the plants in it were collected from the Allegheny River right in my backyard.(hard water to match my tank) Was a fun tank, had so many fish breeding in there, the grandkids loved it.
I like your tank @Bigtrout . I have always wanted to try an Avatar inspired floating rock tank with water falls, just don't have the time for another hobby right now.A good planted tank can be fun to do.

I was hoping frog-pi would be the frontrunner. And nice tank!
My 130g "used to be a reef tank" dart frog vivarium. Hope to soon have its own Dart-Pi controller.
Sorry for the trouble :-(. I can’t recall anything specific for ato sensor going bad upon reboot. I’ll suggest setting up alerts for ato. I am thinking of introducing a safety mechanism where ato will be locked once alert is triggered (based on usage ).
No worry on the troubles it's all part of making this thing work as good as it can. That's one of the things I still need to do is set up alerts. I will be doing some investigating into things this weekend when I take reef-pi off line to add the ph board.
This type of issues are of highest priority for me. I have not tested the baseboard ato yet, did you check theatrus post with float switch wired? I’ll try to reproduce this. I am thinking if reef-pi is turning on ato pump because water level is off (return is off??) or because the sensor has lost power and reef-pi is treating that as water level off .
The locking on alert would be great fail safe for ATO.
