for my tank i had a small card shaped heater
dont buy it!!!! i could never see it work
i would reccomend a larger heater with a knob to change the temp
also the only pump that i have now is the one on the filter
but im getting a small pump for christmas
i would reccomend a pump because the filter pump is pretty weak and it doesnt give much flow
i hope this helps and tell me if you have any other questions
