Is my inkbird faulty

But you want to avoid that from happening frequently. I wonder if there is something that will shut off the heater if it reaches a certain temperature, but allow the built-in controller to do the work otherwise.

Yes, hooking a temperature controller to a temperature controller, then repeating it five times.
I'm just messing, but your best bet is to get a high quality heater and hook it to a high quality controller. Wont be cheap but you'll get the peace of mind.

possibly both of my e 300 heater have display problems they both still heat the water but how well they do it is another question so I have stopped using both of them.

Inkbirdheater contoler paired with a eheim heater has worked very reliable for me going on 2 years now. I would definitely recommend it to anyone.

That used to be my setup. Worked very well for years. Have since switched to jagers on an apex.

Dependent on fish species sure. Frequently as in multiple times a day or frequently as in once a week is quite different. Have to consider when a heater fails there’s a gradual decrease in water temperature. That gradual change most (I’d argue all) fish can handle. What harms a fish is an immediate drastic change in temperature.

When I had native setups in the garage with no heating the day to night fluctuation would be up to 10 degrees in the water. Going from 25C during the day and dropping to just above freezing at night (2-5C) resulted in water swings of around 10. Mid summer my reef tank is set to 78f. The temperature in my old upper level apartment would hit 90s putting the reef up to around 86 for 4/5 hours per day. Again at night water would drop to 78/9/80. No issues, no loss of coral including acros and montis.

I really like my ranco, they don't come prewired though. Can buy them from jehmco or etc supply wired for a bit of a markup. Used in brewing and much more finicky stuff than fish water, built solid.

This is what my inkbird is set up to do. I was just thinking about it the other day: that I don't have it to turn the heater on and off to maintain temp, but as a failsafe if the heater malfunctions and starts to overheat the tank.

My inkbird shuts off power to the heater outlet (where I have the e-300s plugged in) if the tank temp goes over 82 degrees. I have the e-300s set to maintain a 79 degree tank. The controllers in the heaters themselves are turning the heater on and off as needed.

The inkbird will also sound an alarm if the temp drops below 75 (tank should never do this as room is almost always at least this temp) but I don't have anything plugged into the cool outlet.

Again, if temp goes above 82 degrees, power shuts off to heaters and alarm goes off.

I like this setup as I can check temp that the displays read, and I also check the inkbird temp readings.

I should get another inkbird for my QT tanks, especially because one of them might turn into a display. There is less time to act if the heaters fail in there due to there being only 10g.
