ATO Pump Based on PH

[keithb]

I have a young tank that isn't consuming a ton of Calc or really dropping my PH too badly, so for the time being I'd like it to run the ATO through the KalkReactor only if the PH is below 8.2. I am far from a coder, and was wondering if anyone had something I can borrow from?

Logic tree:

If Ato.Low = on
If PH <= 8.2 Turn on exp relay box 1, port 7
else
Turn on exp relay box 1, port 3
do Until ATO.low = off or 300 seconds passes

Try this:

Code: Select all

if (ReefAngel.Params.PH<=820)
{
  ReefAngel.Relay.On(Box1_Port7);
  ReefAngel.Relay.Off(Box1_Port3);
}
else
{
  ReefAngel.Relay.Off(Box1_Port7);
  ReefAngel.SingleATO(true,Box1_Port3,60,0);
}

I'm looking for an ATO based trigger for determination of what pump to use for the ATO based PH... Again, I'm not a coder but I'm interepting the code as Port 7 is always on as long as PH is below 8.2? If that is the case, I will need it to shut off based upon the switch to avoid the great flood.

Would the below be more fitting to my goal?

Code: Select all

if (ReefAngel.Params.PH<=820)
{
    ReefAngel.SingleATO(true,Box1_Port7,60,0);
}
else
{
   ReefAngel.SingleATO(true,Box1_Port3,60,0);
}

Try this:

Code: Select all

if (ReefAngel.Params.PH<=820)
{
  ReefAngel.Relay.On(Box1_Port7);
  ReefAngel.Relay.Off(Box1_Port3);
}
else
{
  ReefAngel.Relay.Off(Box1_Port7);
  ReefAngel.SingleATO(true,Box1_Port3,60,0);
}

Ahh.
Your code is almost there.
You just need to make sure to turn the port off in case the ph is changed mid ATO cycle.

Code: Select all

if (ReefAngel.Params.PH<=820)
{
    ReefAngel.Relay.Off(Box1_Port3);
    ReefAngel.SingleATO(true,Box1_Port7,60,0);
}
else
{
   ReefAngel.Relay.Off(Box1_Port7);
   ReefAngel.SingleATO(true,Box1_Port3,60,0);
}
