Hello - I’m venturing back into the hobby after a 15 year hiatus. Starting small - I went with an Evo 13.5. I’m looking for a recommendation on a solid compact heater for it. Based upon research, it looks like the Fluval M series May be a bit too long for the tank. I used to use eheim heaters and was looking at the Jager 50. But I’m not liking the reviews I am seeing. Would appreciate anyone’s thoughts. Thanks!
