ATO

Hey,

I'm running a nano reef and looking for an ATO system of sorts. Looking for recommendations or anyone who has done a DIY to provide any advice.

Thanks!

I've got a simple pump on a timer that adds a few minutes of water every day. It's not perfect but it works. I do have a float switch that turns off the pump if the water level gets too high.
