Looking for a small nano style ATO. Something like the AA Smart AWC/ATO or Smart Micro ATO preferred as I'm using them on 3 systems already, but will also take a Tunze Nano ATO, XP Aqua Duetto ATO, or other style ATO's where the sensor doesn't need to see through glass and is small in size. This will be going on a small AIO tank. PM with what you have. Thanks in advance!
