Ato float switch.

[Reef.]

I have an aio tank, I have my Eheim heater in with the Tunze nano ato float switch, I wondering is the magnet in the heater likely to affect the float switch? Are float switches very sensitive

The heater is only 2-3 cams away from the float switch.

I doubt there would be any issue there. But, you really should have the heater in compartment one, and the float switch in compartment three.

why the heater in chamber one? Because of evaporation? if that was the reason I agree, was only in the last as it was too thick for the middle chamber.

The first has the media basket, I'll be moving the heater to the middle chamber, as soon as I buy a thinner heater.
