ATO- Tsunami AT1 vs JBJ Auto Top Off

[TreyC2010]

Which of these guys do you consider better? What's the thing that makes it better?

Use both would be my answer. I've been using the AT1 tsunami for many years as a backup to my main ATO which is a couple float switches wired one on top of the other connected to a controller like a reefkeeper lite or Apex. You could combine it with anything like the JBJ. I also have another tsunami at1 as one of many failsafes to my litermeter III doing automatic water changes.
