Best Heater to Work With my Apex EL Controller?

[RedSea500MaxS]

Any suggestions for my 160 gal tank for heater that will work best with my Apex XL controller?

Thank you. My office is very well temp controlled M-F at 73, my tank runs 78 with chiller. But weekends it can drop to 70.

So heater "just in case" is my plan.

Thanks.

Apex just turns a heater on and off so any well-reviewed heater will do.

I used to use Eheim Jager but use Colbalt Aquatics now. Never had issues with either.

I’ve been pleased with Eheim Jager heaters. Anything with it’s own temp control will work though. Set the heater temp control a couple degrees above your Apex programming, that way if it somehow sticks on, it will shut off when the heaters temp control satisfies.
