If and when u do get an ato which one do u think u will get?
I haven't 100% decided yet. An AGO must have three things for me. It must have a pump included, I don't want to guess around and try and match a pump to a timer. It must have an emergency cut off switch, to prevent floods of the first switch fails. And the third is really for my nano, but it must be compact. My tank is a whopping 12" side to side, and that is divided into 3 chambers in the sump area. The pump chamber currently holds my Cobalt Neotherm heater, which horns to be my top off gauge. Just fill to the top of the heater and I know I'm good. When I get an ATO I'll move this into the second chamber. The magnet for the Tunze is sorta large for that chamber. If the Tunze 3155 will fit in my pump chamber, I'll get another one. If not, I've considered the Smart ATO Nano, but I do not believe it has an emergency shut off.
