Plugged into #1 and #2 didn't work on the interval mode, but did work on night mode.
Just realized that interval mode is supposed to be channel one on for set interval then turn off..
Then channel 2 on for the interval while channel 1 is off and so on.
My biggest reason I was having troubles with one being off for a period of time, night mode and interval mode, is that sometimes my one 6105 doesn't start back up on its own without me manually pushing on the prop.
I will try taking it back apart and recleaning it again I guess, then hopefully problem solved! It's hard to get all the calcium off inside the prop housing and vinegar solution doesn't work that well for me on the hard crusty stuff.. Definately going to do more frequent cleanings!
I'll post an update, thanks!! These pumps are amazing and worth every penny!!
