So I have been looking into purchasing an ATO or making one DIY. I found a couple of JBJ ATO systems. I have a JBJ 45g AIO nano tank, so the options were the JBJ Nano ATO or the JBJ automatic top off controller. I like that the controller has two float valves for added protection but the nano ato is much smaller which is better.
Does anybody have first hand experience with either or just any inputs on selection??
