ATO for IM Nuvo 8

Hi Everyone,



I want to get an ago for my nuvo 8. i have been going back and forth on a few. I know Tunze has a great track record, but I am unsure if the 3155 will fit in the back chamber, so I was looking at the nano (3152) but it ply have a since float switch.



I was also looking at the Elos ato. Any Thoughts?
