Help with program for TopOff/Kalk Drip

[JustOneMoreTank]

I am having a little mental roadblock and I can't get this figured out.
I have a Peristaltic pump (like a medical grade feed pump) made by www.reefdosingpumps.com that I use to add kalk to the tank. This is also my Topoff.
I would like to run the pump from 8pm (20:00hours) until 10am, and again from 2pm (14:00hours) until 4pm (16:00hours). I would like the last line in the program to set the limit on the pH as the maximum lets say 8.4 Maybe with a max change time after reaching the pH limit??? Perhaps max change of 15 minutes?

Can someone help me?
Thank you

If Time > 00:00 Then PPD ON
If Time > 10:00 Then PPD OFF
If Time > 14:00 Then PPD ON
If Time > 16:00 Then PPD OFF
If Time > 20:00 Then PPD ON
If pH > 08.4 Then PPD OFF
Max Change 015 M Then PPD OFF

My reef dosing pump from them is not compatable with a timer, any type of timer. The dose rate resets to 0 when you shut the power off.

Let me know how this works for you and what is the trick to get it working.

Thank you for the program collins. I will plug that in. Reading it through it looks simple and direct.

cali_reef... My Reef Dosing Pump is compatible with a timer. It has a power cable that remains plugged in all the time. I had to purchase a cheap stereo splitter from Radio Shack for like 7 dollars and it has a "control jack" in. This allows the unit to "pause" and stop dispensing kalk/topoff liquid if either the High Water float switch is raised in the sump or if the Aqua Controller tells it that the pH is higher than I program.
It works well.... and with this program input tonight it should work even better.

You're welcome

I have the same socket, how are you plan to interface the Aquacontroller with that input?

BTW, pretty wiemer.. My is amost 5.

The interface for the Reef Dosing Pump to the Aqua Controller is pretty straightforward. There is one main power plug for the RDP and that remains constantly powered on. There is a second electrical plug that enters into the RCA splitter that I got from RadioShack. This second plug is what is controlled by my DC8 on and off. If either the float switch or controller plug is powered off then the Aqua Controller turns the RDPump off. When the water lowers in the sump or if the pH goes down some the RDPump will come back on at the correct rate because the main power to the pump was never off. Only the controlling plug.
I hope this makes sense...

The picture of my Weim was a while back when he was a puppy. He is about 5 years old now. He is a great dog.
