Mattrees - the delay on for the skimmer is not too hard just use programmable logic using delay on function.
Thats exactly right aqua_digital, thanks
I didnt think it was a 'very special procedure'

Is there a good guide to follow for this step by step, I really dont find this system very easy to setup, and I kinda really need to get this setup so I can get my regular water changes in check.
Thanks again for everyones time.
