Tsunami ATO Unit

[Wijic]

Anybody ever used a Tsunami ATO for their tank? Did it work all right? I'm looking for an ATO that's affordable, but I want one that's reliable, too.

Those of you who use a gravity-fed ATO, how much higher does the ATO water need to be than the sump for it to work?

Thank you!

I used to run one on my DT and grow out. They work fine. Plenty reliable although I only ran them for about 6 months each.

I ran one for almost 2 yrs with no issues at all. One thing with this ATO is you will get some water fluctuation. I think at the most I got was 1/2".
