Well another question I have on this subject after saying that jim.
If i go with the Timing Switch is it really necessary to go with an on off toggle switch with the timer? I kind of felt like it would have been cheaper to go with just the timer and no toggle?
Due to building my own bait tank tomorrow just wondering what are my options also probably the same thing Halol is doing
