Hi everyone. I am setting up a 28g nano cube that I just bought second hand. Besides the pumps being loud and I'm going to replace them, the heater the guy through in has no suction cups. It's a glass heater. I have a titanium one that id rather use. But can I use either of them by just throwing them in one of the chambers without securing them? Is it ok if it touches the walls of the chamber? The glass one at least has a bumper at the bottom so the heater part it self probably won't touch anything.
Thanks.
Thanks.
