Help with heating supply

[flybyferns]

The temp was 18 celcius. For the last 3 days I didn't turn it off at night because I didn't know. Now I am turning it off during the night. It stays on during the day. I just changed the bulb to a 60 watt bulb as the other was an energy saving bulb and it made no difference in the temp. Currently my best idea is to get the ceramic heater.

This is a good idea ( the ceramic heater) . I use them. They do need some monitoring!
I also use an exo-terra heater cable. ( not in the tank )

I had no luck using a ceramic heat lamp. It made almost no difference in the ambient temperature in the tank. If you do decide to use one, make sure you use the wire fixtures that are designed for them. The regular heat lamp fixtures hold in too much of the heat and end up ruining your fixture. I use blue/red/purple heat bulbs for my tank. They come in various sizes and reptiles/amphibians cannot see those colors in the color spectrum. They are safe to leave on at all times.

Your heating mat might not be working or it might not be the right size to make any difference in that size of a tank. You can always try getting a larger heat mat and using that with a heat bulb.
