Apex Kalk stirring program

[schwaggs]

<span style="font-family: Verdana;">Introduction:</span>
<span style="font-family: Verdana;">This program is used with Kalk reactors that need periodic mixing and settling. The program below will mix the Kalk for 5 minutes, every 6 hours and allow the Kalk to settle for 40 minutes before allowing dosing (topoff) to resume. It integrates with the topoff switches I described in the following post: http://www.atlantareefclub.org/forums/showthread.php?t=48301"><span style="color: windowtext;">http://www.atlantareefclub.org/forums/showthread.php?t=48301</span></a> It will prevent dosing (topoff) during the daylight hours as well as when the pH of the tank raises too high.</span>

<span style="font-family: Verdana;">Fallback OFF </span>
<span style="font-family: Verdana;">OSC 000:00/001:30/008:30 Then ON >>> only top-off 1:30 out of every 10 minutes to limit the amount that can be dosed</span>
<span style="font-family: Verdana;">If Outlet Sump_Fill = OFF Then OFF >>> If the Sump_Fill switch is off, don&#8217;t dose</span>
<span style="font-family: Verdana;">If Outlet Main_Halide = ON Then OFF >>>> If it is daylight, don&#8217;t dose (dose all Kalk at night to limit the pH drop over night)</span>
<span style="font-family: Verdana;">If Outlet Sump2Full = ON Then OFF >>>>> If the sump is too full, don&#8217;t dose</span>
<span style="font-family: Verdana;">If Outlet Kalk_Ready = OFF Then OFF >>>> If Kalk is not ready (mixing or settling), don&#8217;t dose</span>
<span style="font-family: Verdana;">If pH > 08.40 Then OFF >>>> If pH gets too high, don&#8217;t dose</span>

Adjust the OSC command in the Topoff outlet to pump enough Kalk during the dark hours to keep your system topped off.
