A small fan can shave a few degrees if you need room.

Yes, and if I were adding fish when its warm outside and I need the tank cooled off a couple degrees, that is the plan. It means making a screened top for the tank however because I have glass tops. I would need to take one of the glass tops off for a fan to work.

Yup, with glass, the fan would do nothing.
Mine runs with a 1 degree variance forever.
It’s the smallest variance I could achieve.

Ah, the glass top would also be holding heat in.

Yes, there is that too. My main reason was to drastically slow evaporation so I didn't need an ATO since I have seen too many of those fail. Unfortunately, there are trade offs with everything. My tank was set up with so little equipment, heat wasn't an issue until I chose to buy a monster UV, LOL.

Gotcha. The most reliable ATO I’ve ever used was a float valve in my sump on gravity feed from a Rubbermaid Brute trashcan full of RODI lol.

I agree George, the float valve type are definitely more reliable than the sensor type. I have a float valve ATO for when we go on a trip for more than a long weekend and it has worked pretty well except the cheap little pump that comes with it. I have had to replace it already.

Good ATO’s come with 3 separate redundancies making failures (overflows) virtually impossible.
It’s unlikely that 2 different sensors and a timer would fail simultaneously.

Some of the best use infrared with mechanical safety and a multi timer.
Hard to beat.

I probably never spent enough to buy a really good ATO. I am sure none of mine had that many redundancies built in. Like everything else, I guess you get what you pay for.
