Hi mate,
I understand now. bit new to the site. However I have a good understanding of the triggers. I am using a wait trigger i got my hands on, and I have tailored it to my needs.
I have been messing with it all day and I think it may have fired correctly, finally, in the 545gal today. I will double check later and if its not working i will ask for some help.
Thanks again
Kris
