ATO placement in a AIO nano tank

I have the Fluval Spec 16 and thinking of getting the ice cap ATO. I've seen vids of people putting the sensor in the back chamber. I was thinking of putting it in the display. Does it make any difference? Is it more reliable in a particular location?

In a rear chamber it would be more protected from animals....Thats about it..

If it uses an IR sensor, best suited where the water is calm.

Same can apply to floats.. I typically put a "snail guard" around my floats which not only protects from a snail hanging on them but also helps dampen any "waves" in the surrounding water from powerheads/pumps,etc...

Many of the nicer ATO systems have enough hysteresis built in where "waves" aren't an issue but some will just click on/off with each passing wave..

Isn’t the rear chamber sectioned off into two areas on that tank, a media area and a return? Do both rear chambers stay the same water level? It seems like the return area would have a lower water level to account for water leveling out in the event of a power outage. If so I would put the sensor in the return area.

You definitely want the ATO sensor in the return chamber. In AIO tanks, the display and other chambers maintain a constant water level due to the weir and baffles. It’s the return section that fluctuates it’s water level due to evaporation, so that’s where your ATO sensor must be.

Ok, sounds like the return section is the best location. Thanks guys!
