What is a good auto water changer

I use the GHL Maxi stand alone. Once I got it calibrated, it's been functioning flawlessly. I've only been using it for less than a year though.

Confirmed! AutoAqua says they’re coming out with a new unit. No word on when, though.

Think their concept is good, awc+ato all in one but wouldn’t be surprised if they upgrade the interface and add stronger pumps.

I have the AutoAqua AWC. The pumps are quite weak, which could be a problem if you have a mixing station in another room. But it's worked quite well for me, and I like that it's so simple instead of needing/using a full-fledged controller. If you can find a used one, pick it up!
