Good nano heater?

[Joshuakahan]

Hi, I’m thinking about doing a nano reef and I need an excellent heater if I do since it will be in my garage/ fish room. Temps in the winter are 40/20f. My other tanks run on two 300w heaters, but those ain’t gonna fit in a 3-5g. So any solid nano heaters to recommend?
Thanks for any help

Maybe one of those flat Betta heaters

Thanks but those aren’t any good for my purposes

If it’s gonna run on a sump system, maybe put a heater there so it can take up more room and heat without the fish getting burned

No sump, I just ended up going with an over sized heater tucked in the corner
