Temp problem

[Ramon84]

My heater is not correct on my digital display when checking on my apex and thermometer. Tried adjusting my apex to turn on and off but didn’t work was looking to see what is recommended for a thermometer that works with a apex I have a small evo tank

I don't use my Apex to turn my heater on or off. but as a failsafe to turn off the heater if water gets to hot. Using the apex to control the heater can prematurely wear your plug. What heater are you running? Some heaters with a digital display have a calibration so you can adjust your heater. Personally I use Helios, but have used Finnex with good results.

I like an Ink Bird Controller or a Ranco, which is funny because I Googled Danco because I forgot the right name.

Danco Controller

Im wanting to switch to a Ranco Controller for my heater and Am a little confused about how to go about it. Looking online, most people are using them to turn on a cooling device (supply power) if the temperature gets too hot. In this hobby we want them to turn off the heater (Turn off...

A rigorous heater and/ or chiller controller is (in my opinion) foundational for tank stability and fish health.

Ranco Temp Controller

So I'm not very tech savvy and for my biocube the only thing I want to control is temperature. I've read that the rancos are very reliable and was looking at the etc-111000. Has anyone had experience with this controller? Also do I need to buy a temp probe or does it come with one? Thanks...

I can't say from experience how Apex does in this arena, but I have not heard complaints or praise so I made this long post to get the board talking, and here someone else has just posted.

What heater are you using and what is the heater/controller settings vs. actual?

All controllers are hobbiest grade so may vary a little from actual within reason.

More importantly, you also have to be sure probes/sensors have a good flow of water through the full tank, especially in AIO chambers where a heater chamber could get hot, but if probe is in main tank/another chamber, you could have noticably different temps across tank areas. In the EVO 5 specifically, the chamber above pump doesn't have great flow.
