I would say the '4 Fluval Filter' as all my other small filters alwasy get clogged up very quickly and this one lasts ages before having to clean them and even after a month it handles so much more without a clean.
I only bought it for £10.50 from ebay and Viscum Water Gardens have them and said it is way more reliable than the '4 Fluval' and not common from braking down.
Also i just add a pipe attached to the plastic black pipe attached to the filter, the pipe gives out bubbles even without the eheim pump, it only needs to be a small pipe that sticks out of the water.
I have a second item that is sooo useful for everyone and even the fish, it's a small plastic piece that sticks on at the end of the pipe that gives oxygen, it stops the loud sucking noise that it makes and silences it completely.
Since the tank is in my living room but my grandma sleeps there in her bed, it really makes a difference for her.
