Good choice. Aqueon Pro heaters are reliable. Just double-check the temp after a few hours to make sure it's stable.

Placement can affect heat distribution. Ideally, position it near the filter outflow to help circulate warm water evenly. Horizontal or vertical doesn't matter as much as ensuring it's fully submerged and not touching the substrate. What kind of heater did you get?
