warm

31.9°C?! But I'm too broke to get a chiller. This is at Singapore at the afternoon. My tank is Infront of the window.

I heard that heaters could break easily, but mine has a 15-year guarantee so I'm not too worried about it. It has the temperature on it but that can be a little hard to read, so I have a stick-on external temperature marker. Idk what else I'd use. The heater lights up when warming up the water.
