Do you have the timing of how long you would need the doser pumps to run figured out?

Fallback OFF
If Time 01:00 to 01:01 Then ON

Try adding a Set Off statement. Right now there is nothing to tell it to turn off once it turns on.

I will try it..I was thinking that you only needed to put either on or off time and the fallback is what tells it to turn off when not on..if that makes sense to you..it barely dose to me..lol

The fallback statement tells the outlet what to do in the event it loses connection with the apex.

Fallback is key, and so is set OFF. Remember the last true statement wins.

I dose every hour for a more stable dosing regiment, and find it easier to adjust on the fly.

Here is my Alk program which doses for 1:15 every top of the hour (controlled by the first time set 000:00) the next two need to add up to 1 hour as shown 1:15/58:45. So every 58:45 minutes, the doser will run for 1:15 at the top of the hour mark. Now adjusting is a snap by changing the last two times to say OSC 000:00/000:30/059:30 - this will dose for 30 seconds every top of the hour.

Now with Ca, I like to not dose at the top of the hour to split the two up, so here we have OSC 030:00/001:15/028:45 which will dose at every half hour mark. Note the entire string adds up to 1 hour.

Finally, my Mg dosing program doses at the 45 mark on the hour, except between the times of 6am to 8pm as you wouldn't want to dose every hour IMO. The string adds up to 1 hour however.

Lj you would be better using OSC statements as shown above.

There is a Neptune Systems forum (http://www.reefcentral.com/forums/forumdisplay.php?f=368) here on RC. It's really the best place to post your Apex questions.
