I don’t use a heater what so ever. My tank stats are room temp and does great. I’ve never used a heater and if my tank warms up or cools down it does so naturally and gradually.Most of us live in places where the temperatures are considerably colder in the winter time. No matter what season it is though, the goal is to keep your water temp consistent year round. That being said it can be a bit more difficult to maintain warmer water in your reef aquarium depending on certain variables. I noticed yesterday that my tank temperature shot up beyond acceptable levels just because I raised the temp on the thermostat by 2 degrees! Let's talk about it!
Do you allow your reef tank to run COLDER during the winter months? How many degrees if any?
