Heater for IM 25g AIO?

[-Rich-]

I'm brand new to the saltwater hobby and just got my first IM AIO 25gal tank. Can anyone recommend a good heater for this tank?

This used to be a Cobalt brand but they were sold, I like these in nano's.
Fluval E100 Advanced Electronic Heater, 100-Watt Heater for Aquariums up to 30 Gal., A772$56.38Amazon.com30-day returns (most items)Heater
I also like these, big issue will it fit, if you want it in the rear chamber then I would get the Aquael heaters.

Scratch the Aquael heaters, poor reviews, there are not made in the same factory and the quality appears to be way off.
