how to set reef keeper alarm... ato off when PH above 8.5

[majaxx]

Hello,

I want to start using Kalk, so i want an alarm to be set if the PH rises above 8.50 to turn off my ato pump.

When I set the alarm to trigger when its above 8.5 it turns it on when it gets to 8.5 not off.

If I set to trigger below 8.5 its always running.

How am i able to turn off the pump instead of on?

Thanks

Bulk Reef Supply shows exactly how to do this on BRS TV here: http://www.bulkreefsupply.com/video/view/digital-aquatics-reefkeeper-controller/

I set up all the same alarms and shut offs a couple years ago and it has saved me many times.
