Got my ato installed. Was easier than I thought. For some at first when the water level got to the right height, the pump turned off but water kept flowing in. The container was higher than the sump which I believe caused a siphon. So it never shut off. I placed the storage container on the ground ( I just had 2 stacked on top of each other ) and it works fine now. This cost me $70. The Toms aqua lifter pump was $19, the bracket and ato sensor was $39 and it was $12 shipping. Got it in 2 days. Now just got to keep an eye on my storage container and see how many times I have to fill that. It's easier than manually topping off water every or every other night with a small Tupperware container lol.
Here's some pics.
This is from under water
This is where it sits in the sump
This is the airline tubing I have going from the container to the pump then pump to sump. It's resting snug here
And here's the container - water looks dirty but idk why it came out that way I didn't vacuum. Don't judge me lol
