LF Opinions on ATO Units

[DKoKoMan]

Leaning toward the Tunze 3155 now! I bought 2 new sensors for the Neptune ATK and swapped out the old ones. Unit worked for 3 days and now doesn’t pump at all. Waste of money IMO... reliability and simplicity is all I need. Working shift work, often working later than expected, I need to know my return section has water.

Thanks for the feedback folks. Lots out on the market but like I said, longevity and reliability are my key.

I use the Innovative Marine Ti Ato set up. Been bullet proof for me.
I like the magnetic dual low voltage sensors.
Basically a high/low setting.
You can use any pump as well but I opted for the matching IM Ti pump.
