HOB filters are ideal if you prefer a more robust and consistent flow rate and want to purify your aquarium water further with chemical filtration.
Do sponge filters keep water clear?
As the sponge pulls water through its porous surface, it traps debris, leaving the water clean as it is passed out of the filter at the top.
