I had the same thoughts re timer but never found one that would give me 50% or less duty cycle and I found constant on not a problem. I'm on my origonal pump and it's still going. I figure easier to change a pump than mess w a timer.
Amp draw is insignificant.
I used this timer and a relay for a timer on my fuel transfer pump. This is what I'd use and just program the duty cycle I want. For the aerator no need for a relay since it uses so little amperage.
