Help me build my ATO

I did this so far (mine are green)



I have the aqualifter pump.

I was thinking of using this to help to control the top off and so it activates the pump

or this one

cheaper is nicer.  I like the idea.  it will control the aqualifter pump right?

so it will turn on the pump when the lower float says the sump is low.  then it turns off the pump when the lower float says its reached the point where it needs to be.

the 2nd float is just a safety backup?

I like it
