Need help on programming

[gordon2726]

Hi guys,

I want to start dose my kalk water at night only to help balance my ph. I want to start dosing kalk 2 hours after my MHs are off. What's the easiest way to program this? Right now, I am dosing kalk water 24hrs.

This is what I have now:
IF TIME > 09:00 THEN MH ON
IF TIME > 17:00 THEN MH OFF
OSC 001/030 ON/OFF KALK ON

Will this work if I add the following to my program?

IF TIME >19:00 THEN KALK ON
IF TIME >07:00 THEN KALK OFF

Thank you.

You need to create a dummy timer, turned on/off using the 'if time' lines you have above and then AFTER the OSC command add thie line:

If Timer DM1 = OFF Then KLK Off

Assuming the dummy timer was named DM1.

Using 'if Time' lines directly will cause them to override OSC command and the KLK will be on for 12 hours.

BTW; while dripping kalk at night is good (in fact just as good as dripping 24 hours a day) it isn't a good method to stabalize PH. Better aeration (using outside air preferably) would go further than you can with kalk.
