Heater recommendations ?

Been a long time since I have replaced my heaters. What’s everyone using brand wise? Have a 125L with another 50ish gallons of sump/frag tank.

Most would recommend a 2 stage approach for safety.
A heater, like eheim Jaeger plugged into a controller like an inkbird.
Set the eheim to 80, set the inkbird to 78.
If the inkbird fails on, the eheim will shut off at 80, a little warm, but not fish
soup.

I recently tried 2 Finnex heaters with controllers , but neither would work, so I sent them back. I now use Cobalt heaters. Supposedly they are the most accurate at least according to BRS.

I will check out the cobalts, thanks!

Have the heater into inkbird, inkbird into apex for redundancy. Just always grabbed whatever heater the LFS had at the time, have never put enough thought into it. So figured I would ask lol thank you!

Honestly, I've had, Marineland, 2 aqueon and 3 Jaeger heaters over the course of the last year in various tanks. So far the only ones still operational are one aqueon (over 1 year old), Jaegers (7 months), and marineland (7 months).

Inkbird or other temperature controller is a must. The aqueon pro I bought nearly made fish soup, but the inkbird saved me.

Most heaters cycle around 2 points, set point less 1 deg for on, setpoint plus 1 degree for off for example.
Cobalts try to maintain the set temp by turning on the heating element some percentage of time in a 30 second cycle. Like 50% or 15 seconds. If the temp starts to drop, it bumps up to maybe 60 % or 18 secs. I ran one for 2 years but it got encrusted.
Bought one of these 6 months ago, similar heating algorithm, good temp sensor, and I pick the heater to plug in.
